I read an editorial in PC Magazine today by Lance Ulanoff that echoed pretty much what I've been thinking about Facebook - namely that it's in that long downward slide to oblivion, but not many people realize it yet.
And it's a shame, because the reason I signed up was that it was a great way to keep in touch with hundreds of youth who have grown up through my church and diocesan youth programs. Sadly, the plethora of add-ons and plug-ins has steadily drowned out the original purpose, and the quest to get big enough to sell for billions will do to it what it has done to many a fast-growing community before - kill it dead.
Ulanoff points to AOL as probably the first of the internet generation companies or "communities" that died that way. Strangely enough, MySpace seems to have enough user-generated, organic content to survive, even though the software and interface still look like they were designed by a monkey on crack. Well, maybe that's part of it too - better a monkey on crack than some soulless business suits...
