I would like to make my blog fully interactive with posts on various pages which are aimed at different areas of interest.
My question is… How can I make blog posts on the different pages within my blog? The home page would contain a stream of the most recent articles posted on the other four pages.
Actually, it CAN be done, easily, but not with PAGES. WordPress.com is designed to do exactly that.
Use Posts, and categorize those posts appropriately (use as Category name the title you wanted to give to those uber-Pages). Then just put the Category widget in your sidebar and when people click on a category there, automatically a page is generated with ALL the posts in that category.
