Well, the Metaeule is good for more than just aggregating RSS feeds - that would be boring, anyone can do that. Okay, the links are very interesting, but still - just putting together a Planet-like aggregator would be boring.
Therefore, I have now redesigned the search and archive views a bit. From now on, new posts on the homepage will only be posted as excerpts. In the archive and search results, the posts will only appear as titles in the results list - the search is sorted by relevance (as well as MySQL can manage). The special feature: each article or title has a link in the archive. With this link, you can access the secured article page. So even if the original host is not available, the content of the post is retrievable (though only the content that was also provided to me via the RSS feed - if the blog only has excerpts in the RSS feed, only excerpts will end up in the database). Additionally, at the bottom of the archive page, there is a list of posts on the posts themselves that might be relevant to this post - of course only within the limits of what MySQL can manage.
Overall, the Metaeule is no longer just a simple aggregator, but also an archive, a topic-specific search engine, and a cross-reference list. Let's see how useful it turns out to be in real use. Once everything is running smoothly, I will write about which plugins and changes I used for this. Promised.
