Is there a formula to writing popular online articles? Khalid on Invesp blog has focused on the top 100 articles submitted to digg and analysed them. Khalid looked at titles and title length, category, style of content, average number of words in the article, average number of words in the description on digg, and the average number of comments received.
It is an interesting break down to read over a cuppa and for me it confirmed what I had long suspected that technology and business related articles do better on digg than other subject matter.
