I agree with certain aspects to both OS's and Mrs. P's points.
One thing we have to keep in mind, though, is that it
is OK to offer praise within a topic, given that the post is not
exclusively praise.
For example, if there was a topic about the Constitution, and I made an outstanding post that was simply indisputable (

), you could come in and say, "Mike, your view of the Constitution is always sooooo right!" Now, if that was all that you posted, we would have a problem. But, if you then went on to address the topics to debate in a constructive fashion, your post would certainly fall within the rules.
Let me give you another example of what I have seen other forums do in the past, and why it didn't work out.
A lot of forum scripts have "reputation points" or "karma" features. Members can award or subtract reputation points from other members based on their posts. The reputation points are listed in the members profile and within their posts.
It always starts out enthusiastic. The staff of the site implements it in hopes of creating a stronger, tighter community. That usually lasts about a week.
Then, after a short period of time, this all breaks down. Members only add reputation points to their friends, and only subtract points from those with opposing viewpoints. People with high reputation points start flaunting it and skirting the rules, assuming that someone with high reputation points will not be disciplined if they break the rules. People with low reputation points feel slighted and cheated, and feel like they do not belong, which would certainly not be the case.
An area specifically for "kudos" would be perfectly fine at some sites-- for example, coding help forums, pc troubleshooting forums, photography forums, etc. But, we are a political debate forum. By our very nature, our members hold opposing viewpoints and debate in a very competitive fashion.
Let's put it this way: this would be an indirect form of member ratings, and we know you are a big fan of the rating system in the resources directory!
