What I find interesting about the reactions to this are the folks saying "it used to be distinctive and/or unique, but now it's not!"
This is strange to me because the old logo was a regular hashtag. You're used to it looking that way, but in no way is a hashtag either unique or distinctive. The new logo, being a custom graphic, is by definition more unique.
Personally I think it's fine, though I don't think logos matter much at all.
