> Users will have an opportunity to migrate their bookmarks to a Pinboard account, which costs $11/year.
It's also possible maciej wants to ~~do Machine Learning on the data~~, as they have "over a billion bookmarks", but that seems unlikely to me.
I'd bet the "real reason" truly was sentimental:
> Delicious ... is a fascinating piece of web history. ... I bought it in part so it wouldn’t disappear from the web.
Excuse me? "Unlikely"? Understatement of the thread.
And I wouldn't describe that sentence as a sentimental motivation, but rather an _archival_ motivation. Preserve your history or it will be lost.
> Delicious has over a billion bookmarks and is a fascinating piece of web history. […] I bought it in part so it wouldn’t disappear from the web.
Also, not wanting a billion bookmarks to vanish is a good reason. Plus I'm sure he can convert a bunch of former Delicious users over to Pinboard simply by operating the service.
I don't know anybody who stayed with it after that
