Can anyone suggest a theme that has a strong blog component with sidebar for earlier blogs etc??
If you want real flexibility try UiKit or Foundation both would be excellent for this .
I doubt Foundation by its own is able to display an blog archive in a sidebar.
No theme/stacks theme would, unless they used Total CMS or another product
True would need to know what the user intends to use as a blogging tool that would be more important than the theme. I use Armadillo
