"I'm not comfortable with this" (c) can't-remember-name-hero from "Burn after reading"

Past days brought us some news on Twitter and honestly I am very disappointed. This was one socmed tool that was ad-free and very plain, and yet it didn't look like Middle Ages thing or it wasn't a closed community.

what we have now?

a) Sponsored tweets (not getting on my nerves yet)

b) Whoa! Library of Congress archiving all tweets since March 2006! How nice of them! I was just thinking of making a recovery copy!

(a) makes me feel very sad, because ad-free world is no longer such
(b) makes me feel very insecure about privacy and arouses legal issues

The trend just doesn't feel good, oh no.
