'+1' proves that Google is run by engineers.
I, for one, prefer it to 'Like' or 'Tweet'.
I, for one, prefer it to 'Like' or 'Tweet'.
Probably not better than Like, but definitely not worse than Tweet.

I've never heard anybody say they 'like' an article from Wikipedia, but they might find it interesting, so they'd +1 it.
So it is more generally useful. One could +1 a news article about an earthquake or horrific disaster, but might be reluctant to Like it.
So I got the same thought that pathik did - the +1 feeds my personal image of Google as primarily run by engineers.
Not only does 'Tweet' not have the natural connotation of 'Like' or '+1', but it sounds positively dorky to say.
But of course 'Tweeting' is incredibly popular, which I guess just goes to show that sometimes it's better to use a weird word that initially sounds like nonsense. :-)
