Steve, welcome aboard mu43.com - and I do hope you'll become involved. There are many different avenues within this site and there's pretty much something for everyone no matter what their experience with these cameras and photography.
Your gallery of street photography is terrific! Some of the best I've seen. I assume, since you say you're new to micro-4/3, that these were taken with other cameras. However, I'd guess that the GF1 with 20mm pancake would be superb for these kinds of shots. I look forward to seeing more.
