Actually, "let's see what's trending on mastodon." doesn't sound wrong to my ears at all, but maybe that's because I've been around people who say that for a couple of months.

For reference, the community-decided verb/noun for posting on Mastodon is "toot" (as in, the elephant sound), so that would be "can you toot me". I mean. It's ridiculous, but I like it. It's endearing.
