Hello,
    Reading is an activity that covers so much of life.  We read to learn, to feel, to understand, to explore, to create.... Blogging allows people to read and write about their area of interest, expertise, etc.
   I find blogs fascinating.  You type a question into the computer and someone out there has most likely shared an answer,  if not, you will most likely find the question has been asked by someone else and there is a group pondering the answer.
   Starting a blog is easy.  A blog can be as fancy or plain as you make.  It can be written into as often as you like, but information can get outdated quickly. 

 Enjoy!
