To answer your questions:

1. Yes.

2. No, but I don’t care about that. I use Twitter to see what’s happening now, and it’s by far the best tool available for that. If I want to know what’s up if I’ve been away, there are other tools which do a perfectly good job. I’ve got a choice of several and I don’t need another. I don’t, however, have a replacement for the currency Twitter provides.

3. Again, I’ve got other tools for that. If the event’s over, I’ll be able to find consolidated coverage elsewhere: blog posts, Facebook, press releases, news reports, content aggregators, etc. But if, for some reason, I am so committed to having Twitter be my sole source for information (which is silly, but let’s go with it), I can zero in on one or two specific Twitter accounts which I might regard as important and authoritative for that subject and see what they had to say rather than scroll back through my entire feed.

The problem Twitter’s power users are having is that Twitter is the only thing that does what Twitter does nearly as well as Twitter does it. Other things already do a really good job of what they’re proposing to do while eliminating or obscuring the one thing which makes it uniquely valuable now. If they want to add features which make them one more entry in an already crowded field, that’s their business, but if they jettison what makes them distinctly useful, I’ll walk, thanks.
