In blogging, you can freely talk about any topic that you want. I'd like to quote one of my classmates in UP, who just signed up a blogger account about two days ago, because he's both harsh (towards blog nerds) and funny (because he's became a blog nerd now, too). In his first blog entry he said:

Well the "blogging fever" (I think it peaked around 2003-2006, oh and please forgive me for the term "blogging fever") never did hit me. But don't get me wrong, I never did think of bloggers as lowlife nerds who didn't have anything better to do than write what they thought were knowledgeable opinions regarding matters that they deemed interesting enough to praise or well, make fun of *inhales then grins*. -DonRamontiko

It's funny because actually, he's been hit by the 'blogging fever', so to speak.

Anyway, in blogging, you need not be serious or so formal about it, yes you can be of that type too, but what I am talking about is you can be yourself when you're blogging. You need not be imitating other serious, goth-type bloggers to be thought of as a deep person. But if you want to be thought about as a deep person with a healthy intrapersonal value, talk about yoga, for sure you'll get the impression that you want. Anyway, I have even read one commentary that says, Blogging is not a form of journalism, but it is only an avenue to where one expresses his own ideas, thoughts, and experiences. Yes it's true that for many bloggers out there, they only use their blogs as an exhaust of the thoughts that they have. But there are also bloggers out there too, uses their blogs to write their opinions on the current national issues; reviews on movies, literature and art; some bloggers also have made their blogsites as a newsroom--so with all of this, I think blogging too has made its way towards the world of journalism.
