During lunch our writing group at work attended the webinar "Getting a Non-Fiction Literary Agent with Carole Sargent" (courtesy of the UVa Alumni Association. She has a similar presentation already archived at http://www.youtube.com/watch?v=nBlMag_4Iok&feature=youtube_gdata_player
One of the things I've been thinking about is her discussion on having a platform before approaching an agent or publisher. It makes all that blogging and tweeting seem like so less a waste of time! We are just building our platforms!
Now we just need to add speaking engagements, article publication, local radio and tv interviews...
What have you done to build your platform? What audience do you already have?
