On Wikipedia, is it possible to watch a specific section of an article (instead of watching the entire article)? I have contributed to some specific sections of articles, and I want to be notified whenever these sections are modified, deleted, or vandalized by other editors.

For example, it would be useful to watch for changes to a specific part of an article (since I've noticed that thoroughly referenced sections are often removed by editors for no apparent reason, and vandalism to well-referenced sections often goes unnoticed).

No, MediaWiki (the software Wikipedia runs on) doesn't support that.

There must be more to that, then just no. Why don't they support that? Are other web apps capable of doing so? – Jacob Jan Tuinstra Apr 7 '13 at 20:32
Wouldn't it be possible to accomplish this using some kind of script (or perhaps a Wikipedia bot)? – Anderson Green Apr 7 '13 at 20:42
@JacobJanTuinstra Watching a page is relatively simple, since a change to a page can be easily identified in the database. If you want to watch a section, you need to parse the text of both versions of the page, find the section in both of them and diff it. And you also need some way to identify a section. It's well defined what creating, moving and deleting a page is, but it's not so clear when it comes to sections. – svick Apr 7 '13 at 21:51
@AndersonGreen Sure it would, but I don't know about any such script and I don't think it exists (but it's certainly possible I'm wrong about that). – svick Apr 7 '13 at 21:52
@svick I suppose it would be possible. I could write a shell script for this purpose, if only I knew of some way to obtain the wikitext from an article programmatically. – Anderson Green Apr 8 '13 at 2:58
