Want to monitor news and hashtags on \#Mastodon but you live on a small instance with low news flow? I've put VibesMasto News Monitor on the Web so you can get trend and hashtag information from larger instances as well as keep an eye on your favorite \#RSS feed. Completely free, no Mastodon account required.
