Now that people are beginning to understand the way that tags are used, they are using extremely common tags that don't apply to the topic at hand to drive traffic to their idea.
Recommend that the number of tags be limited to some small number, perhaps 10 in total.

How ARE tags used?
Clicking on a tag can get you a list of all other ideas that also have that tag. I've actually found a number of useful things in obscure or unlikely categories based on tags.
The problem is that some posters put a large number of unrelated common tags on ideas in an effort to get more people to view them. Doing this makes the tag system less effective, in that it becomes less likely that I will find what I'm looking for based on the tag fields.
One other possibility might be to only allow viewers to specify tags, with only the most common tags being displayed. This would prevent the author from gaming the idea.
