I'm yet to be sold on it. It is open to abuse - effectively posting whatever you want minus any chance of moderation. I'm not really interested in another Firefox plugin just for this purpose. (Considering there are voting comments/product suggestions/regular comments/ and now stickr) It is getting very fragmented.
It looks like a solution in search of a problem, it is very spammy so you do have to wade through a lot of crap and smalltalk to get to the users with problems or useful comments (if any) and you can only view 5 stickrs on the screen at once (which to be honest is about 3 or 4 too many).
Also on the main site - all I can see are Russian comments. Surely users could nominate preferred languages that they will post and read - and filter out the others.
What about people who do not have the plugin installed, and not having an account - are they still able to read the comments of others? Will users possibly be greeted with comments that are offensive or slanderous to GOTD or to the giveaway software (a competitor slinging mud).
I did find something that works a lot better than the stickr mess... it works like a forum - posts in chronological order - able to live in a separate tab. Perhaps it should be the default when you click on the stickr tab.
