Slack could be the answer to the splintered state of most teams' communications--my team's, and probably yours, too. It's splintered because e-mail is clunky for conversations and gets clogged with attached files. Chat is faster, but its file handling is rarely up to a team's needs, and it can be difficult to search (not that e-mail is much easier).

Currently in a limited preview release, Slack works like many team messaging software apps do, but with a few big improvements: It's cross-platform. It's searchable and very customizable. And you can attach files for sharing, or move files seamlessly between Slack and a cloud service. Slack makes it easier to work without feeling like work itself.

Slack is one window worth having open

By midday, my desktop is a jumble of different windows. In each of my two browsers, proprietary tools brush against story research. HipChat is fast, but it crashes, and it's not exactly a looker. And email...ugh. Email.

Slack is much easier. Each team installation of Slack is called an "instance," and setup takes just a few minutes. A cute onscreen character called Slackbot steps you through the basics of inviting co-workers, sending and reading messages, and setting up a profile. It also sticks around on your team to help in other situations. 

On the PC and Mac, Slack opens in a roomy, good-looking window. The font is legible, and the colors are soothing without being bland. You can use the airy Clean view or the more efficient Compact view. The flexpane (handy for conducting file searches or viewing your team roster while in a convo) toggles open at your command. It's not resizable, so I usually leave it closed.

Right away, you can upload files by clicking the + button to the left of the text bar at the bottom of Slack's window. If you like emoji, you can use the smiley icon in the right of the typing field to add them in either Apple or Google Hangouts style. If you don't like emoji, you can ban their display from your Slack window. 

The Android and iOS clients look similar, but they're adjusted to be intuitive to those devices and make sense on a phone's narrow touchscreen. They are snappy and responsive, making it easy to have a conversation with people on different platforms.

Slack makes email irrelevant to team duties

Co-workers ping me frantically on HipChat, asking if I saw their email. Of course I didn't: It's lost somewhere among company announcements, press releases for religious-historical novels, and all the back-and-forth with others on my team. Then there's the slow, and often fruitless, process of searching Outlook for messages and files.

Slack's search and file handling are among its finest features. For instance, it's easy to attach a file to a message and maintain control of its accessibility. If that message is to Slackbot, the file remains private. If the message goes to a co-worker, only you two can see it. If you send it to a channel, anyone invited to the channel can see it.

I like shooting off quick messages in Slack, but its spellcheck makes it appropriate for paragraphs and longer conversations as well. A co-worker filed stories to me in Slack, and we enjoyed the ease of uploading, locating, and discussing the docs and screenshots in one place.

You can't accidentally delete a Slack message, because you can't delete the messages at all. That's good for project tracking, not so good for gossiping about your co-workers (not that you should be doing that anyway). However, you can delete files or move them to an integrated service, so don't worry about clogging Slack with outdated files.

Slack integrates with a number of popular services--over two dozen at this point, with more in the works--such as Dropbox, Google Drive, and Twitter. Many of them, such as Bitbucket and Github, appeal particularly to development teams. You can also build simple custom commands with the Slash Commands integration.

The bot's no Einstein, but it's no slacker, either

Slack also makes asking for help a seamless part of the experience. If you have a question about a feature, you don't have to leave a conversation. You can just ask Slackbot from a new line. For instance, to get help about search, you hit return and type "/help search". The "/help" command sends your message to Slackbot.

Tiny Speck is the first to tell you that Slackbot is no rocket scientist. If Slackbot doesn't have the answer, you can open a help page from within Slack or message "/feedback" from the text bar to reach Slack's support staff. In my experience, answers usually came back within minutes, and the responses were always friendly and on-point. As nice as the people are, I would prefer to have searchable help as well.

Conversations with Slackbot are a good place to ask the bot to remind you of something, such as "/remind me in 2 days to turn in my expense report" or "/remind me in 30 minutes to eat something." At default settings, the reminder pops up with a sound cue. If you miss the popup, you'll still get a note in your conversation thread.

Cut yourself some Slack

It's no surprise that Slack is so surprising. Tiny Speck developed Slack while running innovative, offbeat MMO Glitch, which closed a year ago this week. Glitch itself was the spiritual successor of Game Neverending, which spawned Flickr. Imagination and elegant simplicity are part of Slack's pedigree.

Slack is currently in a limited preview release. You can sign up for a free preview at the Slack website.

Early next year, wider availability will launch with new pricing. The Lite subscription level (free) will keep a limited searchable archive, restrict integrations to a total of five, and cap total storage at 5GB. The Standard ($9/user/month) will keep a full archive; remove restrictions on integrations; and allow 10GB per user, shared across the entire team. The Plus level ($19/user/month) includes the benefits of the Standard level, with storage doubled to 20GB per user. An Enterprise level ($49-99/user/month) will appear in late 2014. All subscription levels include free native apps for Android, iOS, Mac, and PC.

Team communication can be a tense, tangled snarl of inefficiency. The more I use Tiny Speck's team communication tool, the more my shoulders relax. Maybe that's why they call it Slack.
