Yeah feel free to use slothbuzz tag to share the buzz on anything. I used to say I didn't want actifit posts because, SLOTH but really, who cares, as long as people are using the community/tag and supporting others doing the same all content should be slothbuzz'ing!
Don't forget you can also use the !SLOTH tipbot to share a sloth with friends and help support each other. It also calls the bot to vote on the content based on held tokens by tipper and tipee, I'm just about to craft an up to date post with all the details.
