Since yesterday, I have been changing my site's structure and I am halfway through. Basically, I had around 50 categories in the sidebar on every page. Just like yours, my site's structure was flat.
I created a new page, dumped similar categories (with a few posts) in this new page. Let's call this the "main cat page." I also created sub-pages and added relevant categories.
From the homepage, I have linked to "main cat page" and removed those 50 categories. Do you think this is a good idea?
