Blogging is a communication skill that should be well learned and well used by any writer/author if they wish to succeed in the craft of book marketing.  I, myself, have found this out the hard way.  Not only is it associated with Name/Brand recognition, but establishes the connection and relationship between author and reader.  Most importantly, however, it broadcasts the writer's character and writing ability.  Some simple tips to remember when blogging are these:Always blog to your audience's or group's interest – never go off topic.Always present a positive face or outlook when blogging – no one wants to hear someone vent about any real or perceived injustices in dealing with the abuses and abusers of the world.  Stay focused on subject material and the point of your current blog.Be professional and politely blow-off negative comments or simply ignore them.  Remember the world is filled with boneheads along with people with ulterior motives who want to see you fail. Offer the best you can in information and prose.  The point of any blog is to not only inform, but to entertain.Write often, I recommend once a day.  The more your name gets out there, the more likely you'll succeed.
