So, I have done away with the asides widget, now they are displayed inline with rest of the posts in the main content area. This is because of complaint by one of the readers. Since the asides filtering is gone, my dependency on Ultimate Tag Warrior plugin has reduced. The categories are now the main source of navigation and not tags, but you can read other posts similarly tagged by clicking on a tag. So, categories function as topics and tags function as post-specific keywords. Excuse me for this big change, but the complaint had its merit and I had to heed to it.
