John DeGiglio is one of the smartest people I know, and one of the most relentless developers I've ever seen. If you give him a problem, he will solve it. John and I used to write .Net apps together, and he specialized in SharePoint. He's become an expert over the last 5 or so years.
John's recently published his first public blog articles and CodePlex projects on integrating Twitter with SharePoint.
Twitter Displays Tweets WebPart
How this WebPart came together is documented in two blog posts hosted by Synergy Online:
Displaying Tweets on your Corparate Intranet - Part 1
Displaying Tweets on your Corparate Intranet - Part 2
John's also restarted his blog Backhand Volley at DeGiglio.biz. Unfortunately some good content was lost when Microsoft shutdown MSN/Windows Live Spaces. He didn't get the notification from MS to download his content before it was deleted.
John's also on Twitter @jdegiglio and his Tweets just went public! I expect more SharePoint or tennis focused tweets, John's a huge tennis fan.
