I don't think it's Revel.
I think it's "new".
Another word is "add" or "added" or "addition" or "addendum".
If these words are in the SUBJECT Line, Search Spiders or WebCrawlers will search through the post and report back to it's Search Engine.
Search Spiders (Google, Yahoo, etc.) are numerous and look for new or added information. I believe that's why the high amount of views.
