Hello all, thanks for your interest. To answer some of the comments --
First of all, my interest is not so much to increase interest in my own work. My work is pretty modest compared to the likes of Tao and Gowers, so really I would be happy just to represent the mathematical community and discuss the field I work in as a whole.
I think kragen's comments are essentially correct. I could do a good job of explaining what I do, and why it is interesting, to someone with an engineering background in about five to ten pages. IMHO that is a lot of effort required to either write or read. Of course my impression of HN is that there are indeed people who would not begrudge the effort to read it!
The suggestions have revolved around blogging. I confess that I don't have so much of a taste for this -- I spend a lot of time at a computer as it is, and there are already outstanding math blogs online as pointed out by tokenadult. I would be much more excited to do something that involved face-to-face talk. So perhaps my request is more difficult than the initial impression I gave!
Thanks to all.
