You can individually customize notifications for each person you follow
If you go and look under "Settings > Users You Follow", you see under each username you can edit settings from each user. You can control if you see Submissions, Collections, Characters, Stream, and Journals notifications from each person you follow. You can also straight up edit your Default Follow User Settings (Settings > Site Preferences) so it applies to everyone you follow.
Just like on deviantART! :O Do you even KNOW how long I've been wanting FA to implement a feature like this??
And that's just ONE cool thing you can do on Weasyl! You should read the full journal for the rest.
Party on, guys!
