which ruby twitter library/gem to use?

there is a list of ruby gems for twitter

could anybody recommend me one that is good to start开发者_如何转开发 to learn/use? that have some history of development etc etc?

I want to the stuff below on my linux box

• search for keywords and follow
• autofollow
• rewteet

i'd suggest the twitter gem by john nunemaker. it supports search and retweeting. not sure about autofollow though. there's another list of api clients at the ruby toolbox.
