I registered here a couple of years ago for a reason I don't remember, and I came here a few months ago because I was bored with my other communities and I wanted to get back into pokemon again. I stayed because the people of #smogon were friendlier than expected.
I kinda grew up with pokemon, the anime and then I got the game for my birthday (I think I was like 7 or something) and I've never really left pokemon ever since with the exception of a few months before I came back to smogon.
My team building and battling in general skills have been majorly improved (although I'm still decent at best...) and #smogon forms a good place to hang out in with interesting discussions from time to time. I don't spend all of my online time on smogon, I do other things too, so I think smogon has brought a bit of balance in my e-life!
