Let's think for a second, are there any niches that you wish had more forums than they currently do? Or better yet, which niche do you wish had less forums?
Guinea pigs. I have seven guinea pigs and no forum to go to. There's two big ones Guinea Pig Cages and GuineaLynx, but they are run by and filled with hostile, conservative, and unfriendly people. They have stupid rules that say you must have guinea pig avatars and are very paranoid of people linking to other sites. Your second question kinda makes this topic feel like it's a thread just to make a thread instead of actually caring to get an answer for something.
Second question can be anything. Like, I would say I wish the admin niche had more quality forums instead of low quality ones.
I wish there was more low quality poker forums so I can use them to boost my ranking, but I also wish there was less high quality poker forums so I can take over the niche faster.
If I could think of a niche that I wished had more forums, I'd likely just create one myself. That being said, I can't think of any....any topic that could benefit from a forum, likely already has a good selection of them.
I'd like to see more forums about volunteer work and it's benefits to those who take time out to volunteer at nursing homes, hospitals, elementary schools, and more.
I think more local forms are needed for most topics. For example Eastern Europe has few good internet marketing related forums, wish I could have a quality talk about some specific things only related to our region.
I kinda feel like my time would be better off spent on actually volunteering instead of talking about it. At the same time, I think it'd be great to share experiences of volunteering. I used to do it a lot and I find that I never share those stories any more....but I always love hearing about others who do it.
I wish there were less general chat/off topic forums though. What niches do you think should have less forums?
