Don't worry about increasing your post count. Go for quality posts, rather than quantity. Signal to noise ratio, blather vs bliss, etc. At the very least, it helps when searching your own posts to find a topic. Instead of searching through multiple pages filled with one-liners, you have various topics immediately available.
Also, unless you haunt the forums, you log on maybe once per day. Other people are similar. Putting a quality post up means they don't have to ask you for clarification, everything is right there. They can then ask you a question that is to the point, getting the data in a day or two, vs several days/posts.
It also helps other people. If they want to skip over your post, they can still see everything they need without needing to load extra pages. Think of it as courtesy.
