Of course I would be willing to share. From what I saw, searching social bookmarking sites to try and find adult content, I was left with the following that do:
Blinkbits
del.icio.us
furl
netvouz
reddit
simpy
yahoo
stumbleupon
I don't remember how many I went through, but seems it was alot and these being the bigger ones anyways. There is one slightly possibility on the ones that do not show adult content in search, it's possible with those services, users can still share adult bookmarks?
Sociable is probably similar to yours. I love widgets, drag and drop is nice..
Maybe thats also something you could post about, widgets? Sure make is easy to change around a blog with no coding. Think many people could find them useful.
