What we really need it's a way to filter the posts on regex or hastags.
For instance, I want to follow a developer to have news about it's project I use, but I don't care what he ate at lunch.
Hence the need to filter on #the_Project_I_use
This is possible with #Hubzilla
This could be possible with #Friendica
(I have to dig that part)
Is it possible with #mastodon
? With #Pleroma
? With #MissKey
