Any aggregator needs a plaintext, WYSIWYG, idiot-grade search and collation engine so that if I submit an article about Vonnegut, the system KNOWS that it might go in #goodlongread, it might go in #writebetterdammit, it might go in #writing, it might go in #humor. The system then PRESENTS enough information about any possible tagging that the user can correctly assign one or multiple tags to the content such that it's a non-action for him. Additionally, the system presents other users with the content AND other places where the content belongs so that other information can be presented. Finally, the system connects the content with those interested in the discussion such that they perfect the web.
It's not that we disagree with you on this; it's that it's not very easy to do, especially when there are two coders here, both of whom do this as a secondary thing to what they actually do in real life. That type of search would be a dream com true, but until we have money to hire a couple people, probably will remain a pipe dream.
