Customization options are always good, but the 2 additional side columns will probably contain some ads.

The content space has been shrunk from 4/5ths of the page to 2/5ths of the page by the added columns on each side.

I would seriously consider moving the wiki I work on to another wiki farm, or a private server, if the 2 additional sidebars were added.

I would prefer continuing with the present layout as concerns columns. One column on the left is all there is room for in many cases. See: http://cannabis.wikia.com/wiki/Main_Page

If additional ad space is necessary I would prefer wrapped, right-floating ads. Content space would only be slightly squished by those ads because text would be above and below the ads.
