Raffael from Kaywa has implemented del.icio.us support into my blog, you see my latest links below on the right hand side. If I got them right, Kaywa will integrate this into their admin interface and soon offer this nice little feature for their other customers, too.
It's not an incredible innovation (has been there in other blogging systems for quite some time, and it's barely a dozen lines in BXB), but this has been the first visible change to the Kaywa platform for a pretty long time, so it is a good thing to see in any case. New features are always a good thing. ;-)
So thanks a lot and congratulations to Wanni! Just not sure whether I should perceive this as unpaid beta-testing or generous sponsoring :-)
