SkyGrid, the nifty, free financial news aggregator , is now publishing a stream of news on Twitter, letting users follow breaking business news headlines via the microblogging network. The news aggregator, which only features media on publicly traded companies, not only has an comprehensive Twitter feed for news stories, but the site also has Twitter feeds that are broken down by sector. So users can follow SkyGridHealth or SkyGridEnergy for sector-related news. SkyGrid currently has separate Twitter feeds for 8 different industries. SkyGrid says that the Twitter feed may be especially useful to users who want to access SkyGrid on their mobile devices.
