I'd say it even depends on your target audience. For example, .io domains are quite popular in tech. Other domains never really took off like .mobi for example. If you can spell a word or the name of your company with the domain extension that also becomes a clever trick that can work.

Clarity.fm is an interesting one in itself. Of course it's fine right? We're all here and found it. Though fm would be for radio, right? It's actually for the Federated States of Micronesia. Though it's commonly considered "radio." Clarity is not a radio station so it's an interesting choice, but I don't think it was a problem for anyone.

So it's not as big a deal as it used to be. Though it's certainly still valuable and coveted. It can sometimes be used for authority as well. If you don't buy up all the TLDs sometimes people will buy the .net version etc. They do this in hopes to get people from search engines (or mistakes) over to see ads. The .com gives you authority in that regard. Well, aside from the blatant ads on the other site =)
