I hadn't intended to make this sound negative, per se. But I think there is a pattern that some employ, where self-importance can come into play. We've seen the Silicon Valley darlings move from month to month... Facebook, Twitter, FriendFeed, for example, and I can find examples at each stage. If it did end up being too negative, my apologies. That's what I get for keeping it as brief as I did. There are certainly opportunities for services to continue in a mainstream use role for infinity, assuming they continue to meet needs.
