I myself may be guilty of "diluting" the site as I'm not from computer science or engineering by background, I'm just interested as a hobby, and I joined around a year ago. Having said that, may I ask whether the point hurdle to upvoting is static? If so, an easy way to keep the quality constant may be to mark it up every year in order to account for point cumulation over time or to introduce a scheme similar to the rating of articles (i.e. points divided by time). The "natives" will have been around for a long time and/or will have a higher point/time ratio while interested bystanders/observers like myself will not. Why am I harming myself in this way? Because a few interested bystanders, not synchronized, will do no harm but add more and possibly synchronization and they may even harm themselves unintentionally (not to mention the "natives").
