Great stuff really. But do we really need the comment box on the +1? Please look for the amount of text entered in first days and if it’s close to 0 get rid of it.
It’s also a hassle to +1 people and especially not sure anyone not reading the announcement knows it can be done in the first place. A more transparent interface would be welcome like the ‘rate’ link right beside the rate number.
I actually despise Like systems on forums in general, but I may be in the minority. It usually leads to a lot of dumb posts for the sheer purpose of collecting Likes.
