Digg used to be a hot site for surfacing technology stories, but of course, it then expanded into other areas. This has, inevitably, led to a decline in the relative importance of its technology coverage, and Read Write Web has the latest details, with trend graphs from Richard Cunningham.
The first graph shows how Technology stories, represented by the dark blue area, have as a percentage of all popular stories dropped steadily since the beginning of 2006. To put this into context, on 1 January 2006 tech stories made up 78% of the total popular stories (i.e. stories that made it onto the digg frontpage). By end of March 2008, that percentage had dropped to 18-20%. In fact, this data shows that the percentage of Tech stories made popular is roughly halving every year.
The main sources of front page stories are still Ars Technica, Engadget and Gizmodo, but they are getting fewer stories on the front page than they used to.
It would be interesting to know whether Digg has actually lost its keenest tech users or whether they've just been swamped by the masses. I couldn't say. I very rarely go there nowadays....
