I think they discontinued because it was not as popular as delicious. For the record, I have never used BrowserSync. Delicious has always worked nust fine for me... very unintrusive, and very useful.
I am not sure but it looks like del.icio.us has Yahoo's backing (or do the own it now? not sure.).
I am posting this extract from the doc that introduces a new RDBMS course to Berkley and Carnegie Mellon (Sorry that i don't have a date when exactly it was published!):

We considered both of the leading open source systems: MySQL and PostgreSQL. MySQL has the advantage of significant opportunities for student extension, since it actually comes with almost none of the features taught in a typical DB systems course â" it has no cost-based optimizer, no B+-trees, no fine-grained concurrency control, no recovery, no hash joins, etc.[1] By contrast, PostgreSQL already has most of the features usually taught in class. Of course, this it raises (surmountable) difficulties in inventing assignments where students can profitably extend the system with new features.

And here's the footnote:
[1]It should be noted that MySQL can be interfaced to better storage managers like BerkeleyDB and InnoDB for improved indexing, concurrency and recovery support. We felt that using more than one system was a poor option for educational purposes.
