Before I came across PostLinks.com, I was unable to submit articles. Now, I have no problems. Basically, PostLinks.com is an article submission software product which allows you make it easy to submit articles by way of providing an easy to use interface.
PostLinks.com differs from its competitors due to the fact it includes all of the tools you need. This is very important for the reason that it saves a lot of time when submitting articles. Secondly, it is special is submits articles to Web 2.0 sites. Simple reason why this is significant is because article directories don't carry the weight they used to.
