Long posts can have various purposes. As some think long posts make their post quality look better. Some people think that long posts are better viewed by campaign managers. Again it may be that they can also accept it as a good way to transfer merit. Different people may have different motives. Actually there is no dearth of news channels in present age if one needs to read long post then they can get their knowledge after those news.

What I think effective in forums is that if a member is able to convey what he wants to understand in short form then there is no need to go long. Moreover, not everyone has the desire to wear a long post. There are some things that cannot be explained in detail. The point is that it is a member's perception. Not everything can be solved with restrictions. It is not difficult if everyone tries individually.
