@Rural_Canadian if it was just a few instances on which people specifically gathered to blabber about Twitter, well, that'd be way too easy, wouldn't that? 

@Rural_Canadian btw, there is a public timeline word filtering in account preferences. At least, I can find it in Tusky app.

@Rural_Canadian works for me, added words to my filter: twitter, birdsite... There may be other names for it as well, but my timeline already became 1.5 times more manageable!
