Blogarian Burnout

I have been a professional librarian for all of about six months now, working a minimum of 10 hours per week, and a maximum of 30. This is because I am in a position as a substitute librarian at a public library. Now, I will go on record as saying I really do like my job. It makes me more satisfied to know that I also like working in a public library to the same extent as an academic one, at least to a certain degree and capacity.
I don't typically comment on the work, per say, on this blog, because this blog is personal in nature, and I like to think I can keep my "working world" agendas and needs out of this more public space. Also, because I know that my readership is mostly fellow librarians/new professionals and friends/family, I don't particularly think the day to day of my working life pertain or would interest these folks.
I do however read a number of blogs in the "biblioblogosphere" in an attempt to figure out the latest topics, greatest new tools, or what problems/gripes other people in the profession run into. Today though, I realized that most of the more "personal" in nature blogs that I run into, blogs that use swearwords or legitmately seem sarcastic in tone and tell what-I-was-really-thinking-when-soandso-asked-where-are-the-kids-books, when a giant sign says "kids books" right in front of them. Perhaps I have just not come to the point of job burnout. I find it interesting that people choose to use blogs, read by many people as an outlet for this pent-up anger. While I agree it's best not directed at the patrons that ask the not so intelligent sounding questions...I'm baffled that these professionals use the blog format mostly and primarily to gripe. Sure, I tell my parents about the occasional patron that I feel sorry for because they do not know how to use a computer in this Information Age, but I don't really go into how frustrated I am when they don't take my word (5 times mind you) that their floppy disk is corrupt, and despite clicking other icons they will not get their document back.
What did librarians do to complain about patrons before blogs?
I guess I've just noticed in the past few days that many of these blogs that are by professional librarians, aren't talking about what's new and innovative that they have discovered, or what's on the upcoming conference agendas, it is talk of the "actual phonecall from patron to library X, #64" and the entry digresses into the librarian's annoyance that Patron didn't realize the library closes at 5:30 instead of 6:00.
I apprecaite these blogs on another level though, as to the pitfalls of both needing an outlet for frustration at "stupidity" of others, and as to what type of venue is suited for such display.
It is true, I can be accused of recently telling a few of my friends about a patron at the library. I am sure most of us can be accused of such. Anyone that works in a customer service position, or even works with people in general will run across those events/situations that we just HAVE to tell someone else about. But the consistancy of these blogging librarians in their determination of posting stories about the "problem" patrons or the "stupid questions" is fairly prevalent.
Are they all that fed up with the profession?
