You interviewed yourself?
...
It is a bit shady to interview one self when you obviously have commercial interests, and personal gain from this.
...
Now if we take this one step further: since you published this stuff, what guarantee do we have that you're not making this look better for your behalf?

The point/harm is that interviewing yourself puts a bad taste in readers' mouths, especially if they find this out afterwards. It looks shady. My first reaction was the same as LCJr's ("You interviewed yourself?"). Now if I wasn't a regular here, I'd think "what a douchebag" and probably not bother coming back if this was my first experience with the site. While the Codex doesn't exist to cater to everyone's needs, it also doesn't need to chase away reasonable readers who expect some degree of professionalism when it comes to things like interviews and reviews. Humor jokes are one thing, self-interviews are another.

...pimping your own stuff in what should be a discussion of alternative, less well known independent titles is cheesy and unprofessional, especially in the context it was done. By itself, it would have been somewhat acceptable, but throwing it in with legitimate interviews was uncalled for.
