I've looked at timeline, and it seems good. One addition that would be good in a future release would be to have the clips that you've added one after the other also appear in the timeline.
Here's a link to a blog post that I created with videator:

It's a gym visit (my training partner Nancy and I are gym fanatics). We use very simple effects (the transition ones I hacked together).
We have a pair of video blogs dedicated to interviews and exercise analyses. I'm thinking videator could be a boon for exercise analyses because we could overlay grids, etc. to show range of motion. Here's the URL for that:
Most of the muscleventures site has been done with imovie and videos captured by consumer still cameras in video mode. We are transitioning the site to videator and already our last podcast was done in videator (we still have a couple of legacy imovie ones in the pipeline).
Feel free to put any of these up with a link back to muscleventures.com.
