Why not Blog?

So I was just asked by someone.... Do you Blog? I responded that I did not because since no one listens to me in real life why should I post about it online? Then I read the blog that was being advertised and I liked reading it. So since I felt compelled to comment on someone Else's blog I figured I would write my own. It is not true- lots of people do listen to me in real life. Maybe if I write a blog people can treat my advise like most people- take it or leave it on the Internet. That way I can stop dishing it out to every person I meet like bad cafeteria coleslaw. I am not sure why I am compelled to share my thoughts or advise with people. I guess there is some deep compulsion down inside that leads me to share. I am considered an expert in my line of work and I provide that advise to customers and potential customers on a regular basis. That is the only area that I am actually a certified expert. In my personal life I just try and learn as much as I can in as many areas as I can. I guess I will stop sharing that information on a random ad hoc basis and I will post thoughts here. Take them or leave them. I guess I should bookmark this page so I remember to post.
Areas that I feel I have a lot of experience and can help people are:
IT (either enterprise or home based)
Multimedia- depending on my personal interests- somethings do not interest me so I would decline to talk about them here- such as smart homes.
Automobiles- interesting subject for me. I tie it into my above interest in IT- I like what is new and great in cars- not what is old and low tech. That means that no- I am not going to talk about a numbers matching corvette- but I may want to talk about the brand new ZR1- get it?
Parenting a single male child up to the age of 2.5 (anything after this is still a mystery until I live it) and all related accessories and devices to make life easier or better in this task
Traveling
Life decisions/Money management
Various other topics that I have currently forgotten but will most likely remember if I keep doing this.
Reality TV
Non-reality TV
Movies
