More elements to consider:

- maemo.org has already the basic pieces in place: forum board, wiki, social news, downloads... Localizing these is surely extra work but overall is probably less work than creating the infrastructure from scratch, every time again for a new language by someone else. Unefficient approach? It might be easier to get yourself started with whatever complete CMS without having to negotiate with anybody, but you will have a harder time in the mid term.

- maemo.org is free of advertisement. No contributor is paying or earning money in relation to page views, Google juice, etc. Many (most? all?) of these new sites need to fund their infrastructure themselves and many (most? all?) have some kind of advertisement. To cover expenses... or to try to make some extra bucks? Who knows and how can someone here be sure.
