I think that this site itself could be the basis of a SaaS product. It's awesome. However, I also know from painful experience that time spent on this is likely a distraction from actually building the thing. The happy exception would be if this was indeed the core idea of the thing that you're building. If so: well played. If not: get back to work. ps. Most books are also distractions, but I've heard excellent thing…
One of the major but rarely talked about causes of failure for startups is simply the entrepreneur getting demotivated. Gamefication could be an excellent way to deal with that. Beating yourself over the head and giving yourself a guild complex "Focus! Distraction! I should be..." Tend to build resentment and do more harm then good.
The real way you build a company is by honing a hard discipline: getting up everyday and doing things you have to do whether you like it or not (and usually not). Whether you’re motivated or unmotivated, inspired or uninspired, sick or healthy, confident or afraid. You just get out there and fucking do it, and if you can’t, then be a failure.
A company can stay challenging longer than you can stay motivated.
