Hope this does not have an anti-blog sentiment, but it may.
I really do not read many blogs, to date there has been only one blog that I have added to my Feed reader. Jinsan hit the nail on the head, it falls into the catagory that I can learn from. It is that of software developer. Now I know there are many more with similiar content, I just have not compiled a blog roll as of yet. I will be compiling one and hopefully will have at least ten to maybe twenty that have interestig reading that is not boring.
One thing I find offensive is the need some find to use the F*** word a lot, I myself go into tourettes syndrome and use it in speech but in a blog, no!
Personality/entertaining are added pluses.
My reason for a blog, the birth of my son, while I realize that may be boring to some, it was meant to be a personal diary of his life from birth on that someday he will appreaciate.
