It really does not matter what your favorite field of interest might be, you can absolutely be sure there are a ton of other people that share your passion for the subject. If for whatever reason, you want to pass along the knowledge you already have, and acquire more of it in the process, starting a free forum is a great way to go about it.
The internet has changed so much in our lives, and one of them is the ability to acquire information about obscure subjects very few people know about, or care about for that matter. A forum is a place where people gather online that have a similar interest, and impart their opinions, ideas, and understanding of it.
Let’s use as an example “How to Grow New Plants Discovered in the Amazon in the Past Twenty Years”. If you were planning on starting a forum, it would be pretty difficult to find a more limited or vague topic to start one on it might first appear. However, if you were to dig a little deeper, and think about it a little more, your target audience could be quite large.
So, who would be interested in a forum of this type? First, obviously people that want to learn about new plants discovered in the Amazon. Second, how about people that just want to know more about the Amazon? Third, of course conservationist, they will read anything even remotely connected to the Amazon.
Fourth, the “How to Grow New Plants”, in your title is going to attract home gardeners, and we all know there are a ton of those. Fifth, what about people that want to learn more about Brazil, and other countries in the region? Sixth, you could always add a section for “Eco-Tourism to the Amazon”; after all, that is already a large and growing industry.
Seventh, here is one you probably did not think of, “Fishing in the Amazon”. It is one of the last places on Earth today, where you can fish like you would of 1,000 years ago before man ruined so many of the great fishing destinations. Eight, of course, all botanists worldwide would be very interested in the forum.
Those are just a few thoughts on who could possibly be interested in a forum on this topic; there are many other good ones too. A good owner/operator of a forum will be sure to read all of the comments and threads that are placed on the forum, and then will respond accordingly to the member’s interest by starting new sections that apply to those pursuits.
This was just a simple example attempting to explain that no matter how immaterial or unpopular, you might think the topic you want to start a forum on might be to you or your friends. In reality, it could be just what hundreds of thousands of other people all over the globe have been waiting for. In conclusion, there is no wrong topic to start a forum on, but only a lack of execution beginning it, and perseverance maintaining it until it explodes out of control.
