One of the best things is surely how we feel less alone with our problems. Crossdressing seems more normal because we know there are SO many others out there. We're not even a small minority in society.
This gives us the awareness that we are sufficiently many that we can demand to be treated and seen as relatively normal. Many of us just don't know that yet. But the truth will ultimately win.
I don't think the internet helps with finding partners though - at least not for me. I know some people have found their matches like that but I wouldn't even know where to look because I don't trust dating sites.
