I'm with you there. I still fondly remember Google Buzz and haven't really found an alternative that has the same feel to it yet.
I hope there is some post facto analysis a few months from now. IMO Google is risking that this shutdown effectively causes the migration of a few hundred thousand Brazilian Google users to Facebook.
For me, if I were a Blogger user, I'd take it as a sign that it's time to migrate. Honestly, beyond some of the core stuff (gmail, contacts for android and keep), I don't think Google has much vested interest in maintaining most of the services that were once offered out of their 20% program. It's funny, but I now trust Google to keep supporting niche products far less than even Microsoft.
Then again, for me the catalyst was when they killed reader and iGoogle. The Old Reader, and others have largely taken it's place, but that integration into my home page was truly useful to me. Now, I'm far less likely to catch an article on any given day, I check HN almost daily, and a few others not quite as often, but it isn't the same... and it isn't my typical blogroll anymore.
