Blog? What to blog?

A friend suggested I get involved in the blogsphere. I have been a lurker of sorts. Mostly viewing blogs when I got hits based on searches. But, I am forced now to ask myself, "why blog".

Why Blog?

• Like many times in my life, I am going to just start [to blog] and see what emerges. I fear that this may be yet one more opportunity for me to sharpen my narcissistic tendencies. I hope not. It may provide me an opportunity to keep a log of my life that I will appreciate and reminisce about as I age. Perhaps, others will view these posts and find comparisons and contrasts to their own lives. Who knows where that could lead?
• My father-in-law and others I respect keep paper logs and find that doing so adds value to their life. Of course, these logs are private and not shared. So, one of my first questions about blogging is: How much should I reveal about myself? I expect that I will wax and wan overtime. Thus, I will post stuff only to later edit and delete it.
• I have a strong interest in technology, especially software engineering. Maybe, this blog will be an opportunity for others to join me in my constant voyage of discovery in this realm.
