Any major news publication that aligns with the vertical of your product or service is relevant to you.
PR for tech companies is cheap / free advertising.
It's not that TechCrunch is still relevant or not - because we're not really discussing the quality of their journalism or what they represent. We're talking about the staying power they have for a readership that's interested in tech.
So in that regards, yeah definitely - TechCrunch still drives tons of page views and click-through's so anytime you get an article there, it can't hurt!
