After years' of developing, now you can see forums everywhere on internet, every niche has thousands of forums out there, and there all kinds of topics on these forums. For example, niche cash advance has cash advance forums, online dating has dating forums, even more, you can even see online casino forum out there! Now you see that there are millions of forums online. Why are they developing so fast? In fact, it is easy to understand if you know something about internet technology. The reason is it is very easy to build an online forum. There are forum softwares such as VBulletin for you to use, so building a forum is as easy as installing a software on your PC.
So now we can understand why online forum is developing so fast. But one problem we must mention is many forums are just trash, they are useless. But just as everything has its good side and bad side, so this is not strange at all.
