Here are a few things that are going on in the back of my mind.
> I'd love to see a time based filter. For example, consider the evolution of JavaScript libraries. For simplicity's sake, let's take the shift from prototype to jQuery. What you guys are creating could effectively answer this question: 'When did jQuery surpass Prototype as being the premier library, and why?' The filter would have to be periodic (since votes are going to be spread out), but I would find it fascinating to glean the shifts in developer technologies. Think Backbone, ember, angular, etc..
> I see a lot of ULs in place of what seem to be 'features'. While this may only be relevant for things that are capable of being compared (apples-to-apples so to speak), I imagine significant value will be come out of a resulting table of comparison; that is, if each bullet point could somehow be categorized, tagged or curated in some way. This may be hard to achieve (and may not be relevant in some cases), but you could effectively build out a report highlighting things that _are_ and _are not_ available (instead of having contributors write long lists that then users have to parse and reconcile). Does that make sense?
> In the blog post you state "we aren’t actually trying to tell you what the best programming language to learn first is" -- I appreciate that you don't want to suggest the 'best', but I imagine that's how most developers (particularly newcomers) are going to interpret the results. I'm curious if such a forum would influence new developers for the better or worse.
> Sign in with Facebook? What about stack exchange/github? I don't know what you guys think about leveraging reputation, but it would be nice to bring my existing recognition - score and tags (albeit slim) - along with me. Even integrating LinkedIn could be interesting with skills. Just a thought.
