as a new plugin / extension of Web?

[lodriguez]

This was mentioned briefly on IRC last week. I'm not sure how you want to add this to the web plugin. Here is my idea on how to add it: https://github.com/lodriguez/Limnoria/commit/b282498080bb23dff39d3ec88b9c03e2e552ddad

You don't need to fetch the list of providers; the title snarfer already downloads the start of the page so it can look for <link> tags

[lodriguez]

That was my first Idea, but discovery sucks. Many sites don't have it in the link tags, so we would start adding workarounds for sites like reddit again.

[progval]

Alright, it should support both then. Open a PR with support for both registry and discovery, configurability, and a couple of tests and we'll work on that. Also, the registry should be downloaded when it is needed for the first time (and in a thread) instead of in the __init__() in order to not make the bot hang while it's downloading.

[lodriguez]

Fair enough, that's why I commended here first.
