I usually only get my friends thoughts about the stuff I write or participate to (because well actually who else I'm supposed to ask ?), and I think it's important that people can leave their impressions / thoughts or comments about something they liked/disliked. Personally I like to have lots of comments about stuff I do (just like I like to comment to help people) because well sometimes there's stuff you can't realise because you're obviously stuck in your own point and view and can't necessarily be able to see the thing from a different perspective. It's human I guess.
So here's a small list of stuff I'll try to keep updated. Feel free to comment, comments are always useful.
