Is this why tonight, searching Facebook was borked? Totally useless. To be honest it's falling apart anyway in terms of usability - I've heard of too many reports of people being unable to find people in searching: a pretty major failing in a social network. I've experienced it enough myself, along with months of posts randomly going missing.
Give or take the falings of Microsoft or Apple, at least they make tangible products. Even Microsoft - nominally a softare company! - makes products you can touch. I very much doubt FB will be around in 10 years time. Its primary function - contact - will probably be usurped by IT tech generally; if not, an open-source conglomeration of other "social networks" will successfully compete in its back yard. Even Google offers a service, but at some point I imagine its search function will be annulled - within a decade or two. Probably the latter, since predictions of technology are never sooner rather than later - flying cars, anyone?
(Actually, having learned to fly, I now know the dream of flying cars is a "never" rather than "later" - just shows what a bit of knowledge does, eh?)
I don't dislike FB particularly, but it's just another AOL.
