As a reader (LOL) I find it to be a strong negative signal when someone identifies prominently as a reader, puts that in their Twitter bio, wears T-shirts or caries tote bags with reading-related slogans, et c. For some reason it usually turns out that they almost exclusively read young adult, trashy genre fiction, thrillers, romance novels, that kind of thing. Which is fine! I read garbage sometimes too! It's fun! But people who watch reality TV, 24-hour news, and Lifetime movies, don't wear shirts with... hold on, let me find some of these reader t-shirts with an image search:

"Obsessive TV-Watching Disorder" or "TV watchers gonna TV watch" or "Eat Sleep TV-Watch" or "Never underestimate the power of a girl with a TV"

Not sure why things are that way, but I'd go out of my way not to broadcast a "reader" identity, for this reason.
