I would say ...

out of the dark, into the light of understanding or comprehension

when light is being shed on something, it is made to be understood or made comprehensible

I just found a weblog named "clog"in which one of the bloggers explains that she "clogs" since she doesn't want her identity to be disclosed. So I am taking a chance here. "Clog" seems to be an offshoot of "blog". It's just a wild guess at this point.
Second, I write as an anonymous cog because I am larger than life, mythic even. (And not mythic because I don’t actually exist. The other kind.) At least on this blog, I stand for experiences greater than myself, if not quite universal. Rather than seeing myself as just a chick who writes personal things here, I prefer to present myself as a cog chugging away in the great academic-industrial complex. For I have come to see that (coggishness? coggery?) as my fundamental position in academia, and I wish to explore how the cog, as a facet of academic labor, works.

2) it might be a reference to a very famous Honda commercial aired in Australia in which there was no trick photography, so I venture another explanation " cog= say it as it is, be honest".

Sorry for the typo. It's "cog" not "clog"
