Would it be worth having a "number of years riding experience" field in each users profile? I was recently in a thread that became a little lively. Both view points debated their sides as well they could. On one side were riders with 100's of thousands of miles experience debating with a rider who, it later turned out, had less than a years experience. That doesn't necessarily make the experienced riders correct or the inexperienced rider wrong but it does put their view points more into perspective.
In this particular thread it hardly mattered a bit what the outcome was. However if the topic was more serious then there's the danger that new riders could be treating as gospel the view points of riders who have less experience than themselves and I think that's quite dangerous.
