The solution is hash tag my friends. Follow who you like, to see what's going on with the laser eyes #bitcoin
For coffee it's #coffeechain
The plebs? #plebchain

To some (little) extent yes, but it's a different thing. No always aplicable, not everyone uses (the same) hashtags and also it is not sorting by my rules. I have no say in what is included under a hashtag.
Making my own filtersets (as complex as I like) and applying them with one or two clicks is a very different thing than searching for a hashtag.
