I'm probably going to try migrating my bookmarks over to historio.us.
At the very least, a Delicious-themed landing page with a "how to migrate your bookmarks" and a few emails exchanged with bloggers who've lamented the loss of Delicious ought to draw a few more people's attention to StavrosK's site.
Oh ok, I didn't know it was different. I thought it's just a bookmarking app. In any case, importing delicious bookmarks would be helpful to everyone involved.
