The place I work at had a big convention last year in December (2010) and we heavily promoted participants to use twitter to interact online. Now I am trying to go back and see if I can fetch all the tweets that used the convention hashtag and possibly save a copy locally. I did twitter search but it does not go as far back to see the tweets.Is there a way to search this far back in Twitter?
Is there a way to fetch all of my tweets and save them on my computer?
