There are loads of useful tools to help you track buzz, your brand / product conversations, competitors, etc on Twitter. One that’s definitely worth playing with is Trendistic

Below (it looks terrible small on the page but you get the idea) is a static embed showing the buzz following Derren Browns prediction of the lottery here in the UK last week. Notice how there is a regular low level buzz for “lottery” throughout the time period but it peaks hugely with the Derren Brown spike as people discussed the event for the draw on Wednesday night ( and “how he did it” - the second spike accompanying the follow up show on the Friday. )

Love to hear your feedback and see your graphs (usethe comment below and embed function on Tredistic

We were talking to a potential client yesterday about a b2c social campaign, and the Moonfruit Twitter campaign was one of the examples we discussed. This reminded me that at the time we did a quick social snapshot of the buzz the campaign generated, and thought it would be cool to share.

Full story here on mashable (under the title “Twitter Promotion done right” ) if you missed it. The basic premise was that if you tweeted #moonfruit, you had the chance to win one of 10 Macbooks. As you can see by the number of mentions (until Twitter somewhat contentiously pulled it as a trending topic, see Moonfruit’s own blog here ) this was -whatever your view on the rightness / wrongness - a very cute savvy campaign,  generating over 100,00 conversations (or at least, tweets)  over a couple of days.  The tag cloud, right, shows mentions for squarespace, who ran a similar, earlier campaign.
