A blog? Is that edible?

This was my first reaction when friends introduced me to the whole new world of blogging. From Wikipedia:

A blog (a portmanteau of web log) is a website where entries are commonly displayed in reverse chronological order. “Blog” can also be used as a verb, meaning to maintain or add content to a blog.

Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketchblog, videos (vlog), music (MP3 blog), audio (podcasting) are part of a wider network of social media. Micro-blogging is another type of blogging which consists of blogs with very short posts.
For me, the verbs which describe my blog are:

Relate. My blog started as a perpetually updated email to my friends living in far-off places about what’s happening in my life, which then mutated into a tabulas, friendster, multiply and wordpress blog. Keeping in touch with friends has been a breeze, thanks to this technique. In the relational aspect, my blog is a roaring success.

Express. A place for my two cents’ on various topics such as books, movies, current events, etc. This blog also serves as a sounding board when I am trying to make a decision, since I need to put my thoughts down before they make any sense. Also, it is a convenient vent for my emotional turmoil and QLC rants.

Earn. Eventually, I am toying with the idea of this blog or a separate professional one as an alternative income stream.
Most of the articles I have read online advised me to specialize in order to attract readers. Unfortunately, I am beginning to have an allergic reaction to the word “focus.” Easier said than done. Choosing a topic is a pretty big committment since I would have to avoid writing about other things that catch my attention. This blog is basically about my life, hence it is a glorious mess topic-wise. Also I don’t see myself as much of a writer. I am an adherent of stream of consciousness writing. I prefer to read, writing is the lovechild of my lifelong affair with books.

So, help me please? What topic can I focus on?

Personal finance. I love reading personal finance blogs, and I’ve noticed that there aren’t that many PF bloggers in the Philippines. I’m thinking of a PF blog for Filipino quarterlifers/ young professionals who want to get know how to be good stewards of their money.

Language Education. Or related to teaching, training, English, books, writing. Okay, this one is still pretty vague bacause I have not come across any good sites on language education yet. But I hope that soon, I can apply what I’m learning in grad school, so that I can finally blog about it. It’s write to make stories out of theories.

Something else. For other suggestions.
