- why your decision to be active here was in favor of Bitcointalk
I'm not interested in talking about the two forum you mentioned in the thread, but I wish I could provide bit of opinion on bitcointalk.
Despite all its merits, the bitcointalk forum is where Satoshi Nakamoto usually posts. He is the founder of bitcoin, so when you want to support bitcoin then of course you also support forums where lots of people are talking about it. This is a very short opinion, but I hope you get the big meaning out of it.
