Being a writer of two extensions for the DotNetBlogEngine I've honestly not installed any non standard extensions on my site... until now.
As
you notice there are some links inserted at the bottom of each of my
post, these are some social bookmarking sites that a lot of folks use.
I honestly don't, but I do know that a lot of people do.
With all that being said Danny Douglas wrote an extension that does this for me. So if you run DotNetBlogEngine and want to have the links on your site then go check out his extension.
