Featuring other artists

So, I think I've gotten enough of a handle on this blogging thing now that I want to start doing some small features on other artists. I have lots of ideas, but I want to keep them somewhat short (so I can actually accomplish completing one every week! ;) ), so I'm looking for any comments on what you would consider to be essential in a spotlight on another artist. More personal information to get to know the artist, or more focus on their work? Should I stick to a certain type of work (probably two-dimensional pieces since that's what I know about), or should I expand to whatever catches my eye and have more variety? Any opinions are welcome! :)
