I've never been a consistent Twitter user, so much of this is of little to concern to me and I have thus not been following the details so far. Still, I decided to check the site just now to get a general idea of what's going on. Something I have noticed, which has yet to be brought up, though, is just how little the rest of the world cares about this. I follow mostly people on the Japanese side of the site, and as far as I've seen, not a single one has brought up anything about this ordeal. They either do not know, or do not care.
おはようございます~, people say every morning, just as they did before the purchase began. They also tweet a lot about what restaurants they've eaten at, or their thoughts on whichever video games they're playing at the moment. Meanwhile, nearly every single one of the English-speaking users I follow has, in the past 24 hours, posted about where to find them in case the site goes down, along with other occasional comments on the purchase. Despite what I've seen postulated by some before about some aspect of the Twitter economy which causes people to act more hostile, the 日本人 seem to be able to maintain an overall positive demeanor --In the circles I'm familiar with, at least, I'm sure you can find examples of the contrary-- and the drama which is so usually associated with twitter is rarely present.
Just thought that was interesting.
