Conquering a Niche on Squidoo

When you want to conquer a niche on Squidoo is it better to have a separate account or is it better to have all your lenses on 1 account?

There are differing opinions on this...personally I like to set up a new account for a new niche and make all the lenses in that account relevant to the niche. You can then make your entire profile relevant...link all your lenses together by lensrolling and using the featured lenses module...and come across as an expert on that topic.
