I've been working with reprint content sites for a while for some of my clients. I've noticed they are pretty rigid and it is quite difficult to find the content my clients really want. So, I've designed a sort of reprint article search engine and I'd like your feedback. I'm hoping some people will find this quite useful. Some things that separate it from the existing "big guys" free article sites are: 1. indexes authors, articles from hundreds of different article directories 2. recognizes common authors between different article directories 3. RSS feeds will filter by your search terms and possibly specific authors (again, pulling from any directory the author may post to) 4. (eventually) email alerts whenever the search engine discovers new articles matching your search criteria I have some more ideas as well, but I think this is a good start for now. Currently, it only deals with reprint articles, but eventually I think it could index other types of free content as well. The "proof of concept" is up now at contentsleuth.com, and I'd appreciate any suggestions and feedback. I hope this doesn't come across as spam... I have not publicized the site yet at all and I really do value any comments. Thanks in advance.
