For example you can't subscribe to grugq for political-infosec content without some IRA memes. And I don't mean that other people shouldn't post stuff they want, just that I'd like to see a filtered view of their posts most of the time. After a few iterations I gave up Twitter almost completely.
I wish Twitter allowed people to tweet into different personal channels, and I could only subscribe to the personal channels I'm interested in.
Social networks badly need to evolve. What they are currently is quickly eroding the social fabrics.
But, I have all Twitter alerts turned off, and only check every few days. I rarely look at my own Twitter timeline and instead go directly to people's timeline who I have found will have the news I'm interested in.
It's a blazing fast way of accessing Twitter content.
