The essential purpose of langpop.com is to establish which languages are most popular. Implicitly, most people coming to your site are trying to work out which language is 'best'. The obvious strategy is to work your website towards answering that question and in the process gaining more information about your visitors and their purchasing intent.
As it stands, the only thing we know about anyone on your site is that they have some vague interest in programming languages. The more concrete our picture of your visitors, the more precisely we can target advertising, the better it will convert and so the more you can charge for it. The Adsense algorithm tries to do this implicitly, but it does it relatively poorly.
For example, the "about the languages" section could be expanded massively, with a (keyword-dense) review of each language and (affiliate) links to books, tutorial material, IDEs, code review tools and so on. Adsense links on these pages should see better bids and better clickthrough, but that's entirely secondary.
