Mashable is one of the best (and only) Blogs that will really keep you up-to-speed on what's happening (and what's not) in the Social Media realm.
The trouble with all of this content (and, we're not just talking about the mass output of Mashable here, but all Blogs and news sites) is that the information flows like a fire hydrant, and the best shot any of us have of really ingesting all of this digital content goodness is to use a news reader (like Google Reader) and an online bookmarking tool (like Delicious or Google Bookmarks). Even with those tools, it's still hard to aggregate and edit your content. It's even harder to really spend the time reading, understanding and letting it all truly "sink in." So, when a post like Mashable's Social Media Guide for Small Businesses gets published (as it did on December 4th), it bears being Blogged, Tweeted, saved and thought about.
If you're in business and interested in Social Media, do yourself a favour: stop reading this and go spend some serious time reading that Mashable post... and take notes (there are some real gems and stellar links in there).
It's all right here: Mashable's Social Media Guide for Small Businesses.
