Aggregation is the new content, apparently. Used effectively, pulling together similar feeds into one source can be highly effective. Used badly and it's simply online prostitution.
Of particular interest around these parts are the micro sites for Herne Hill and Dulwich that have just been rolled out.
Developer @lloydsheph is keen to aggregate blog content next. And there lies the challenge: pulling in RSS feeds is relatively simple; building a site with relevant blog content stripped from elsewhere needs some editorial guidance.
Hopefully the planetarium concept will come close to reaching the modern interweb gold dust of hyperlocal that we are still waiting to happen effectively.
