No, not because of attitudes like that. This isn't a dating site.
But let's break this down a bit.
First of all, while there may be 23000 registered users, only a fraction of them are active. Probably at least a few thousand of them are banned spammers, another portion are banned members, and then you have those that register and never post or come back and then there's those that only post once and then leave. Add to that all the older members that are still registered but left for whatever reason. All in all, there are probably only, maybe if you're lucky and putting a positive spin on it, a few thousand people that are active.
Second, not all of those few thousand that bother to post are single, many people here are married or have a partner. And those that don't aren't necessarily looking for someone. And on top of that, even if some people are ready and willing to date, that doesn't mean they would want a long distance relationship, which is, more likely than not, what would happen when you meet on a forum.
And lastly, just because this is a forum for lonely people does NOT mean that people come here looking for a date or someone to love. I would imagine that most people here simply want to be with people who understand them, find a group of people that are like them, that have the same problems as them. That doesn't, in any way, indicate that they want to find the love of their lives.
So yeah, when it all boils down by the numbers, you can maybe find a few people who want to meet someone or are lucky enough to start talking to someone that they mesh well with and start dating. As I posted earlier in here, there is a thread for single people, as it's likely buried, that would indicate that it's not all that popular....at least not anymore.
