Link Incest
I have to agree with "Jon", Gruber (John with a h) does have a habit of linking to sites that link to him regardless of how good they are. For instance, this link list entry was a complete waste of time…
I wonder if there's any limit to it?

Although cliquey, it’s far less annoying than sites whose links that don’t link to the intuitive reference, but to the category link on their own site. Tagging gone horribly wrong ending in a disgusting display of self love.
