I'm always on the evil Facebook, and have noticed with increasing regularity that the system hangs and crashes. Sometimes on the full site and more often than not on the touch version that my phone uses. I assume its to do with them updating various services.
Don't use it, or anything similar, myself, but while I believe it has its downpoints for someone like yourself, "in the trade" so to speak, to come out so firmly you must have some fairly strong reasons?
Is it personal or can you share them?
Don't want to hi-jack the thread, just interested.
