In opposite to most commentators here, I had quite a pleasant experience in online relationships. I've been dating wth a girl, which Ive met on Craigslists personals section. I agree about a lack of intimacy in such kind of dating, but this problem can be solved with face-to-face meetings. For me, Craigslist wasnt a site for chatting, but a platform for meeting someone with similar interests. Sadly but recently it has been closed. I found a list of alternative resources here -
https://websiteslikecraigslist.net/, but I dont have an account on any of them yet, so if you will share your experience I will be grateful.
