What is with the Google [Bot] and Bing [Bot] etc.? I see them all the time, and when I go to who's online, it says reading topics. What does that even mean?
Google, Bing, Yahoo, etc. don't just happen to know what is on nearly every page on the web. Rather, the corporations write programs (bots), called webcrawlers, that visit pages and index the data they find.
So, when you see that Google is reading a topic on the site, that's Google indexing the page for its search engine.
"The poet only asks to get his head into the heavens. It is the logician who seeks to get the heavens into his head. And it is his head that splits"
