Everyone's interests aren't shared. It's taken me a while to come to that realization. Even when someone's interests are the same, the manner in which they want it implemented is vastly different. I'm not sure if this is a concern for you, but just an example of what I've gone through.

As for the rude people, that's going to happen. It seems like it's more prevalent lately, what with the influx of new RPers or those that haven't RP'd for years on this particular forum (since all forums with RPing are vastly different). Soon after I began RPing, I realized what I wanted and realized that most others couldn't fulfill that for me. So, I went to GMing. And though I'm still learning how to GM effectively, I've found it (generally) more rewarding than just being a player. 

I've met RPers and GMs that I have learned to never go near again. There are plenty of times when I've seen a fellow RPer behave rudely and have to bite my tongue. I've had RPers come to me about an RP I wish to start and criticize how it's run and the mechanics. I just explain to them why I've decided what I've decided in a civil manner and expect them to not return, knowing it's not for them.

I've been trying to get a couple RPs to go for years now, trying the same one's over to see if a new (better) crowd is around, but alas. I'm just going to keep trying. The thing with such a large community like this one, you really have to be patient. One of my IntChks to an OOC has 20~ bumps in a row from me, and the OOC is completely untouched. But I understand that the way in which I want the RP to run to fit my desires is not the same as others, and I think that's what we need to take from this. 

Currently, I'm in an RP of a genre that I didn't consider going back into, but the GMs seem cool and I liked the plotline, so I joined. I've subsided from bumping my hopeless RP every other day to every week. I guess it's just persistence and patience.

Otherwise, I've just written stuff on my own and started a project that could become a novel if I ever got the self-esteem and confidence that I could do it. I've tried to get into other arts (drawing, singing) but they don't fill the same need. So I guess it'd be best to just keep looking or start something yourself. Be open and expectant of failure ('cause that's what the majority of this forum is). Just because you want it now doesn't mean it will come to you. And just because you've wanted it for months doesn't mean it's going to sit in your lap and give you puppy dog eyes. If you want a specific role-play and you've started an IntChk, don't expect it to get any views. Bump it if you have to.

But I will warn you about the general state of players right now. They're pretty poor, so don't take a CS as a sign of commitment in the slightest. There seems to be no real cure to people disappearing. :/

And I'm sorry if this is depressing or pessimistic, but that's just how it is, sometimes. I wish you the best in your endeavors, though. I hope you find a source of creative entertainment. :)
