Hello, what's new?

Hi guys, my name's Steve, and I'm from the UK. I've been away from IM for a while, what's new? I've seen a couple of Google updates that I've missed (SEO-wise). Are affiliate sites still going strong? Which ones are best to get into at the moment? Amazon, Clickbank? Are micro niche sites still a good idea? What are the odds of getting banned from Adsense because of them? Thanks
