Dear Joe User,
Over the past few months the level of activity on Jow User has risen very nicely. In some categories there are voer 50 articles posted a day. This is great but it also creates friction issues. It becomes obvious that some users would prefer not to see articles from other users. The solution is a user filter.
If you find a particular user rubs you up the wrong way then you add their name to your personal filter list and no more articles from that person appear.
Simple, yet very powerful. A second filter to highlight articles from those people you like would also be nice.
Paul.
