What was blogging to me

Blogging...  I could not figure out the point of doing this action.  I thought of it as a diary that everyone can read and that you apparently want them to find and read it. What a joke!  Then I thought it was frustrated writers that maybe did not make it as a writer and decided to voice pages of a book that they could not complete but it seems as if blogging has to do with communication and a way of people to express that want to "talk" to someone and have them reply back.  They probably are looking for people who think like they do and cant find it in their everyday cycles of life but can find it here in the virtual pages of the Internet.
