Why Blog?

Like other unfinished business this Blog space has begun to worry me. It exists, patient and fidel, waiting for me to turn my attention to it; while I, feeling somewhat helpless, contemplate and discard possible posts. In the meanwhile I visit other blog spots wondering what others write about, cynical and dismissive at times, admiring and awed at others. Sometimes I seek inspiration, at times respite. I confess that there are times when reading what others have written is simply an act of avoidance: avoiding having to write anything on mine.
I feel a bit like a philandering husband who, leaving his long suffering wife at home visits other more colourful, vivacious and intellectually stimulating women!
OMG: such is the habit of the mind, that even a blog spot can induce guilt!

Frankly, in spite of reading a wide variety of personal blogs, I cannot understand the purpose of one. According to me it is just another way of being verbose. another way of being an egotist. Another way of doing what the world is already doing....communicating via a one way street. Sure people post responses, but.... but the joy of communication ( read verbal, read email exchange) is in its dynamism. In the flow of the thought and conversation that is shaped by the other. And then in the way that your conversations shape you! It is evolution. Conversations have the power to transform. Do Blogs?
