actually, while you could replace google search with bing or duck duck go, what would really destroy the world is the sudden absence of gmail/google docs/android updates/youtube, all of those things could be replaced, but it would take more time...
Always wondered what happened to you. Followed your story a few years ago when you participated in Baremetrics/Open. Glad that you held on for a good sum and exit!
I vaguely remember the 3char screen names and the trading of accounts or lists. If I recall correctly there was underground stuff going on with trading those names. Thanks for hitting that memory switch for me.
I'd think you need to take into account a few other items such as:
Network Usage (What business segment is using it?)
Upcoming Deliverables (Are current issues being resolved, active development?)
Features
Awareness (Is it in the press? Is press good/bad?)
I'm sure many industries are supported with the likes of "Just Google it"
