@Gargron I think Publish is much better than toot fwiw!
Also, I think we should reevaluate the term "Reblog". I know I'm just one person, and this isn't a huge deal so take my opinion with a grain of salt, but the prefix Re means to do something again, and none of the other language used insinuates there was ever and initial Blog. I think Boost is still fine, but also Repost and Republish are better options, with my money on Boost and Republish. There's my unwarranted opinion for the day lol
