YouTube – How to Subscribe to Comments

I just installed Youtube Comment Retriever. It is a Chrome extension. When you watch YouTube video, you can open side panel, where you will see comments sorted from highest rated.

I haven't found similar add-on for Firefox, but there are some other nice plugins (eg. YouTube Comment Snob) that can at least filter undesirable comments.

I'd make 2 changes to @eisb's suggestion:

1. That is an invalid playlist Id, so try "8DCB3F2E1AF98B48" (Cronoslogic's 'Hubble Space Telescope' series), but more importantly
2. Use 'base' rather than 'api' in the URL, e.g http://gdata.youtube.com/feeds/base/playlists/8DCB3F2E1AF98B48

In the documentation, it says "Similarly, if you prefer to use the base projection, which is well suited to feed readers, you can substitute base for api in any of the sample requests described in the API documentation." It seems the api projection is more for developers.

I've just added that to Google Reader and it works fine.
