Are you jealous of those cool expanding sidebar archives in blogger, with the little arrows that expand the month to show all the posts?
Well you can have that in wordpress with Collapsing Archives
http://wordpress.org/extend/plugins/col ... -archives/Install. Drag widget. Configure widget. Profit.
I don't currently have it installed because... well if you have a blog that posts around 30 a month, the long list looks ridiculous. However, if you are closer to 10ish posts a month, it looks awesome. Relevart uses it, so here's an example. Observe his sidebar. Notice the opening and shutting months when you click. Oooh.
