I have implemented Twitter widget on the bottom of my forum to show the most useful topics from my forum randomly.
See here: www.webmastersgossip.com
I have created a separate twitter account specially for WG, its @wg_tweets
I will be tweeting only valuable topics on that account and they will be appearing at the bottom of the forum. You can also treat it as Archives but it will show only valuable topics, not all topics.
I think it is a good way of using the "Footer" area because usually people don't go to footers but now if they go to footer they will find some good topics which may have buried but they can still be seen through the tweets
What do you think about my idea and implementation on the forum?
