While watching our Twitter feeds in December, my friend Primož Škerget and I noticed that people weren't writing anything positive. There were bad news, bad comments so we had the idea to make Twitter more positive, for at least in the time around Christmas.
We made a simple webpage, where users could write something nice for the person writing something nice after them. The user would then, after posting his own nice comment, get something nice from the person that left a nice comment before him/her. Basically like a snowball of nice comments.
The responce we got was quite nice (even the TheNextWeb staff noticed us) and some of the comments were really sweet.
