library weblogs update?

I have an idea which may be useful or may be totally redundant. So I’d appreciate some feedback on this before I think any more about putting it together. I know a bunch of comics bloggers use Comic Weblog Updates, which seems to be based on a script based on pings to I’m wondering if it might be useful to have a similar source for library blogs.

Reasons not to do this:

We have lisfeeds already.

Reasons to do this:

It might provide another way for people to pimp their library blogs. We don’t have lisblogsource around anymore, so if people choose to have their blogs listed it might provide a way of discovering new library blogs.

It might promote more serendipitous library blog browsing.

Any thoughts?
