Not really? There’s not an entire genre of fiction titled “techdirt”, nor is it utilized by literally any other media company to market their goods.

The only way for a trademark to be generic is if its utilized by large swaths of the market for advertising (i.e “Taco Tuesdays”) or is overly generic and descriptive (i.e. “crab fries”). Techdirt is neither utilized by large parts of the market nor is it generic and/or descriptive.
