hashtag_retweet_bot
hashtag_retweet_bot is a ruby bot that retweets all twits tagged by a certain hashtag. It's ideal for conferences, meetup groups, communities, etc. As an example, let's say you want to retweet every twit found with the hashtag #icecream every 5 minutes (300 seconds). This ruby gem will let you do it as easily as running:hashtag_retweet_bot icecream 300
This bot was born as a little script for the Scotland On Rails 2008 conference. We saw it in action there and as it was nice and useful, so we forked it to adapt it to our needs at the EuRuKo 2009 conference.
This year, Tomasz Stachewicz from the EuRuKo 2010 has adapted and modernized it so that it works with Bundler, OAuth, native RT and some other improvements.
We can expect the EuRuKo 2011 will go ahead and improve it for the next year :)
