I don't have to know you to know what the reasons might be:
- or you have some friends here
- or it's about money
- or you've simply gotten used to this place like others, e.g. to Facebook ;]
- or you're naive as I wrote earlier and you believe, despite all evidence, that something alternative and sensible is being created here.
Generally, it doesn't matter whether I know or not your reasons ;] It's rather you who should ask yourself whether YOU know why you're here and also whether you're definitely aware and certain that your goals are definitely consistent with what you have here. because maybe you only thought that was the case because you don't know the whole truth or maybe your never think about that ;]
