So @researchbuzz (follow them!) has created a Mastodon URL Helper tool (for desktop, probably won't work on mobile) and it is a REALLY good, simple tool to quickly show the information from your username on Mastodon, including your RSS info. (Did you know if you put .rss after your username you can see your own feed from here as an RSS feed??)
My results from using the URL helper are attached here as the image -- and try it out for yourself here:
And make sure to poke around on the rest of https://searchgizmos.com -- there's all kinds of great stuff on there.
