The Digg effect

A story that hit front page had a link to http://www.floodle.net in it and as a result I got a part of the Digg effect though not the full force. I like to analyse my stats when this happens to get a feel for different types of users, here are my conclusions for Digg users. Statements are generalisations of course but are for the average Digg user..

Things I know (in general):
Digg users don't click ad's (partly due to ad blockers, the ad click ratio plummeted and the ad total barely moved if at all)
Digg users mainly use firefox (over 50%)
Digg users don't use Linux (about 2%)
Digg users don't browse sites, they only look at the one page submitted
Digg users appear to be quite young based on type of stories that get dugg
Digg users don't return to dugg sites after the initial visit so getting dugg is not a way to get regulars.
Digg comments are never as in depth or as technical as slashdot comments
Digg comments are also much lower in number than slashdot comments
Digg.com, by asking users to feedback on their advertisers, is virtually begging users to click it's ads. Another sign that digg users are not generally consumers.

Things I suspect:
Digg's Alexa ranking is overinflated because Digg allows people to post story links to users own sites and people who own sites are more likely to use the Alexa toolbar. Most slashdot users would not install Alexa because they consider it spyware.

Conclusions
Having a story or web page dugg makes a peak in your stats but it is a very steep up and down spike with little after effect.

Not being a technical site it's unlikely floodle.net will ever be "slashdotted" however I would welcome any comments from site owners who have been as to their conclusions.
