While some things you say might be correct, you need to think of that this is teh intrawebz. The thing here is that everybody can be anonymous and say what they want. If you want a place to advance, go find a job, do not use an internet forum because that is not what it is made for. It is made for people to have fun and have a good time together for the most part, which I am having. For some reason you aren't and therefore you decide to leave, that is your choice, but I honestly think that you can not blame it on the community, you have nobody but yourself to blame if anything.
I am not sad that you are leaving because I think that, at most points, you have been acting like an attention and power-hungry whore. I went there. Anyhow I wish you good luck on your further life, and I hope you realize that internet is not always srs bznz.
