I think this is nonsense.
Limbaugh had a very successful web presence and souvenir store, as well as his long-standing newsletter The Limbaugh Letter. He may not have been on Twitter and Facebook, but his staff certainly lurked here at Free Republic.
This may be a case of cause-and-effect, perhaps that social media filled the void after Limbaugh's passing, not that Limbaugh ignored social media.

So, how many of you have Limbaugh ties and scarfs. Sometimes I wear one of them and ask people what is special about them. Sadly, no one knows Limbaugh’s bold red, blue and yellow motifs. Remember members of congress wearing Rush ties?
