Links wise there's nothing much out of the ordinary. We certainly don't part-take in buying or selling links. Here's the inbound links as
returned by Yahoo. There's certainly not a massive amount of links there and this is something that needs to be increased. There's nothing there which I'd consider to be dodgy. The subsidiary domains have all been 301'ed to the main site now so any duplicate content issues should in time be removed.
Should there be an issue with the type or quality of those inbound links why would this affect the number of internal links reported in the webmasters tool panel?
