It's possible that you've either arrived on this page simply by arriving on this page (as in right here).
On the other hand, you just might have arrived here from this page (as in over there).
If you've arrived from over there, you'll know what I'm talking about when I say that, if you picked #3, you have answered correctly! Congratulations!
A JoBlog is indeed "a journal about your job/career."
If you'd like to learn more, you can go to the JoBlog group (looking is absolutely free). As more and more people get JoBlogs, links to their blogs will be added to the group.
You might, or might not, be interested in having a JoBlog of your own, but you might find at least some of the various JoBlogs interesting to read. If a particular person's blog catches your interest in a special way, you can send an e-mail to him/her once you become a member of Writing.com. You can become a member at a number of different levels--including the free level.
That is the level that I'd advise you to join first.
At the free level you can have a limited amount of items (writings) in your portfolio and can participate in various activities at the site including messageboards, contests, corresponding with other members, and other really cool things.
The next level up is the basic level that will, among other things, give you more space to share your writings (if you're a writer).
The upgraded level is the first level where you can have up to and including 10 books (which will be the level you'd want to be at should you decide to create one or more books/blogs/etc.--and, of course, that could very well include a JoBlog).
There are three more levels about the upgraded level: premium, professional, and enterprise. I was premium for several years and just recently upgraded to professional when a year's membership was on sale.
Anyway, I hope that you'll at least join our community for free so you can write e-mails to us and give us some feedback on our JoBlogs. Here's mine!
