I just can't get value out of Twitter, for this very reason. I know you can use any social network for any purpose, but for me, Facebook has always been about following friends and family, and I enjoy the content. Twitter has always been pushed as a way to be "in the know", but no matter how hard I try to 'curate' my feed, I find that following people who I don't personally know means that most of the tweets I see are worse than meaningless, they have negative value. So my entire feed ends up being either ads, or content I don't want to hear about from the people I follow for other reasons.
