I so wanted to post "This is my first comment", but i refrained. Bet it would have been funny though.
I don't mind them, I generally will read them in hopes that I get "some" background on the person posting like who they are, what they do and other general stuff like that. It's like a book, you read the jacket to get the basics of the book. If it doesn't catch you in that little blurb then you probably won't read the book. It's one damn post. It's not the end of the world. If you don't like it, don't read it.
Why do people feel the need to post a blog about their first blog. How does that help us? At least some people have the common courtesy to say “Hey this is my first blog” AND include some nice technical information. I wish I could bill all the people that wrote about it being their first blog. It is a complete and utter waste of time. What is more annoying is that these people are supposed to be the cream of the crop so to speak in our industry. Do us all a favor and skip over the “This is my first blog” crap. I dare you to be different.
