New blogroll denizens

In a fit of housekeeping zeal, I went on something of a blogcrawl (like a barcrawl, with less delirium, but about the same amount of nausea) to find some new deserving blogs for our roll of bloggery.

The most notable thing was the shocking number of blogs that link to us (see for your self). The sheer mass of them had never hit me at once before. A fair number have petered out already, but a lot are still active. As I think I said before, this math blogging thing is gonna be BIG.

Perhaps the biggest surprise was that my old friend Jesse Johnson (we went to Budapest Semesters in Mathematics together 7 years ago) now has a blog on low dimensional topology, which I somehow managed to look at months ago without registering the identity of its author. Jesse is (and from my recollection, always has been) a real low-dimensional topologist, as opposed to myself who is egregiously faking it (and yet somehow I still manage to get myself invited to conferences). Jesse and I also seem to have a remarkable knack for following each other around the country (we both went to college in western New England, grad school in Northern California, and now he’s at Yale, and I’m in Princeton on my way to MIT). We’ll have to see how long we can keep that up.

I do recommend perusing some of the other additions as well. Neverending Books and Ars Mathematica both have extremely deep archives that I have barely begun to spelunk, and I’m definitely intrigued by Charles’s attempt to do algebraic geometry from the beginning at Rigorous Trivialities, though I’m sure the series reads pretty differently for someone who’s already read Hartshorne.

  1. About half of the links in that google search come from John Armstrong’s blog, and there are several other redundancies. It seems the blogosphere is not a very sparse graph.

  2. you, sir, either need to delve deeper into the google results, or change your preferences to show more per page (my preferred solution). I promise that people other than John Armstrong link to us occasionally.

  3. What can I say? I find worthwhile stuff here to refer to.

    Meanwhile, most of the entries that link to my own place I recognize as the “website” field of comments I leave elsewhere…

  4. I am not aware if you know this already, but if you visit and submit “” in the search field, it will show that your blog has “authority” 63. This means at least 63 blogs link to yours. But, there are lots of people who use RSS readers to keep up to date and they will not be reflected in the “authority” count.

  5. Vishal,
    You can actually see how many Google Reader subscribers any given feed has; SBS has 292. For scale, that’s about half as many as the n-Category Cafe, and a 1/4 of Terry Tao’s. Hey, if we’re each individually as popular as 1/32 of Terry Tao, I figure we’re doing OK.

  6. Vishal, I had not looked at Technorati before, and the statistics are interesting. It seems that as of five minutes ago, we’re the 116,930th most popular blog. Woot!

  7. Well, if you’ve already read Hartshorne, then of course it will read a bit differently. But it’s not really the main source that I’m following (just looks like it from the last couple of posts). Plus, I’m going to avoid the word “schemes” for as long as humanly possible, and stick to varieties. I promise that I’ll do some things that aren’t covered in Hartshorne (at least, not as far as I know…there’s a lot in it that I haven’t gotten to yet).

    And from my admittedly small sample (ie, me) Technorati authority and readers seem to be reasonbly connected. I’m at about half of yours for both measures. Anyone who knows the first thing about statistics willing to look around and see how strong the correlation actually is?

  8. I added Jacques Distler’s blog Musings, which often has good math in it.

    And I want it noted that we are not having as much fun as we might with the comment tags on the blogroll.

  9. One interesting thing that I found on Jesse Johnson’s blog is a list of upcoming conferences. Perhaps, we could have such a list too. Could we have it on the RHS (say below blogroll) with links to conferences that we hear about.

  10. Incidentally, the idea for the conference listing page came from Ben’s post a few months ago about how hard it is to find upcoming conferences. Having the comments box at the bottom is helpful too, since a couple of people have pointed out conferences that I didn’t notice on my own.

  11. @Joel,

    I just added a “conferences” category to our links. From the WordPress “dashboard”, go to “Blogroll”, “Add Link”, and make sure you uncheck the “blogroll” box, and check the “conferences” box instead.

    Right now, all that’s there is the Georgia Topology Conference, May 14-18, which Ben and I will both be at — and your collaborator Sabin Cautis too.
