Oh yes GAG is VERY addictive - TILL one doesn't realize it lol I log in as many times a day as possible myself but again I'm not hooked on to it. I realized it's 'addictive properties' a while ago and now I prioritize my work obviously and then I do miss out logging in for a day or so at times :-)
Definitely. I stop myself after 2 hours on this site per day otherwise I just sit and answer/browse questions forever.
Like I've said before, it's like being a wallflower at a massive party where anything and everything you can believe it going on: people are fucking, talking about politics, arguing about religion, sharing recipes, giggling in the corner, etc. etc.
I really like it but I'm not addicted because I'm still capable of completing the things that are more important. Things related to work and my career I mean. I still manage to get that done to the point I need.
