Snippets and microformats are becoming very popular on the web and Google loves it. This morning as I was randomly searching on Google UK, I came across the following.
As you can see Google is listing local business address, a review from an authoritative source, number of reviews where applicable and link to Places Page in SERPs. We all know Google always experiments with new features aimed at improving search experience and those folks at Google HQ are giving local search alot of attention and rightly so. Should Google push these new set of features live, it will make microformats, snippets and business listings very important (not saying they are not right now).
