Category size
What do you think (that is, if you care at all)? I divided a “Math Teacher” category out of “Teachers” so that none of the lists on the side would be more than 10 – 15 long. More readable? or doesn’t really matter?
Also, was it fair to categorize blogs by what the author does, rather than what the blog focuses on? Hal likes books, but he’s a math teacher. ‘e‘ writes about teaching math, but she’s not a teacher. Sarai studies serious math, but blogs about nature and knitting and enjoying living simply. And I placed some people in the wrong slots. In the end, does it matter? Maybe one long, alphabetic list… And how many are hard to slot? Fred does unions, ed policy, and social justice. Homeslice is a teacher, but he does teacher unions exclusively. Is there a better way?
(Also, I need to list out lots of teacher-additions and bow my head for a few more deletions, but another day. )

It is more readable. Is it worth it? I don’t know. Trying to categorize them is tough, for the reasons you listed. As for a better way… not sure. It would be nice if there was a way to list alpha and put a few descriptors (but then that would entail updating if the focus of someone’s blog changed, so maybe not).
And now everything is sitting in the wrong category. I’m contacting wordpress for this one.
Seems like a lot of work to me, especially since many of us, despite our content areas, often converge in our thinking and writing.
Hey, as Bob Seger said:
I take my card and I stand in line
To make a buck I work overtime
Dear sir letters keep coming in the mail
I work my back till its racked with pain
The boss cant even recall my name
I show up late and Im docked
It never fails
I feel like just another
Spoke in a great big wheel
Like a tiny blade of grass
In a great big field
To workers Im just another drone
To ma bell Im just another phone
Im just another statistic on a sheet
To teachers Im just another child
To irs Im just another file
Im just another consensus on the street
Gonna cruise out of this city
Head down to the sea
Gonna shout out at the ocean
Hey its me
And I feel like a number
Feel like a number
Feel like a stranger
A stranger in this land
I feel like a number
Im not a number
Im not a number
Dammit Im a man
I said Im a man
I take it that’s a vote for no categories? :-)
