I follow many Twitter users who I think give great advice* * *
For those of you who, like the writer, find this one a little confusing, the need for a subject pronoun here is best illustrated with the choice: "I think THEM give great advice" versus "I think THEY give great advice." Cleary, the action of giving in that clause needs a subject, and "who," like "they," is a subject form.
So if I can so easily understand that, why am I still completely baffled by the Twitter phenomenon? Why would anyone care that I'm changing the cats' water or watching "Family Guy" reruns?
You know, back in my day, we had complete social disconnectedness -- and we liked it!
