Ask HN: What's the matter with delicious.com?

After several owner changes it seems that delicious.com has a new owner. The service quality seems to lower since then (sporadic errors when adding a book mark), the design was uglified, the domain is del.ico.us again. And now the site is effectively unusable since days. Even the blog doesn't work anymore. http://blog.del.icio.us/

All this is not professional. I'm worried about the future. Does anyone know what's going on here? What bookmark service do you use and recommend?
