Yes, we are based in London and we will surely look forward for the next Twitter Developer Nest. We have seen twitterjobsearch.com, but jobmigo.com relies on entirely different principle. Unlike twitterjobsearch.com, jobmigo.com does not index all job related posts, instead, it relies on users to retweet only the interesting posts using #rtjobs hashtag. The aim is to separate out the 'most discussed' job posts from the overload of results given by other aggregator and search tools.
