General market size information
The following series of charts shows the relative traffic for several social news and/or bookmarking sites. The first chart shows that digg has about 7x the traffic of reddit. I am using these two sites as benchmarks for the two charts after that. (Each chart can only compare five sites.) In the first chart, digg is the benchmark, while in the second chart reddit is the benchmark. Again, remember that digg has about 7x the traffic of reddit.
The second chart shows the relative traffic of digg, stumbleupon, slashdot, propeller.com and fark. Here you can see that digg is approximately 3x the size of the next busiest sites, stumbleupon and slashdot. Propeller and fark are no more than 40% of the size of those smaller sites.
The third chart shows reddit as the clear size leader, though mixx (which only came onto the scene in any reasonable sense in May 2008) is growing quickly and relatively steadily. Newsvine is showing some signs of growth as well. Both dzone and sphinn have maintained a relatively steady amount of traffic for the last year.
The fourth chart shows traffic comparisons for sites that are more focused on social bookmarking than news. There has been a clear growth in traffic over the last year with CiteULike and Diigo leading the way. Over the same period of time simpy has lost traffic, ma.gnolia has maintained, and Connotea has grown significantly.
The fifth chart shows the relative traffic of the two largest social news sites (digg, stumbleupon), the largest social bookmarking site (delicious), and a smaller, but growing, social news site (diigo) — which can barely be seen at the bottom axis.
