Otaku Crush’s site is still in beta, but feel free to check it out. It’s a dating site devoted to getting people with the common interests of anime and manga together, though you don’t have to sign up to read any of the news posts or essays.
Feel free to check out the rest of what I’ve written so far. Also, while I cannot really say anything about the dating aspect of the site (having never used it and all), if you feel it’s a good opportunity for you, you can also sign up. At the moment, it’s free of charge.
