Motivation:
Most of the time, there would be people which find (La)TeX but is not sure about whether it will suit their needs or not (e.g., see this question). These people want to see the capabilities and some "results" of using (La)TeX instead of only code.
Given that most FAQ's and related sites provide only code for people who already use (La)TeX but are facing problems with the code, newcomers have problems with finding samples of compiled source code and visual examples to evaluate whether it will suit their needs.
Proposal:
Would it be good to have a compilation of examples of the capabilities of (La)TeX, a la texample, in which new comers or people that is discovering (La)TeX can see the wide range of usability of (La)TeX. Can we summarize the (La)TeX features here? or it would be better to gather those in some other site, like extending texample over than TikZ?
For example, I know that (La)TeX can embed code and format it, draw music, include figures in really complex ways, what else can you point out? Can we produce a (hopefully) complete list?
