I found an interesting request in Scoble's blog:
But Yahoo's API doesn't look like they really gave me what I wanted.
Here's the first thing I wanna try to build: a search engine without blogs.
Seriously. Blogs are increasing noise to lots of searches. We already have good engines that let you search blogs (Feedster, Pubsub, Newsgator, Technorati, and Bloglines all are letting you search blogs). What about an engine that lets you search everything BUT blogs? Where's that?
Well, explain something to me - how does a search engine differentiate a blog from an arbitrary website? It's not as if their labelled in some universal way (nor will they ever be). He then goes on to state that Yahoo's API "isn't good enough" to support that. Earth to Scoble: that might be because you asked for an impossible feature. Sure, we could have an engine omit things listed in those indices. The trouble is, it's not as if all blogs are listed in those indices. Second, there are things listed in those indices that aren't blogs - Feedster, for instance, indexes RSS and Atom feeds. I know that I've submitted non-blog RSS feeds to feedster.
I might as well as for a DWIMD (do what I meant, damnit) compiler...
