You can build a feed that contains the exact stories you are interested in from Digg.com. You can filter by: description, category, submitters, number of diggs, and number of comments.
DiggFiltr.com is a very neat page. Still under heavy development but the core feature is very useful already. I instantly created my own filtered Digg.com feed by applying a few filters on the sections I’m interested in. I can see this site getting really popular if the developer goes in the right direction with it.
One thing that I also liked was that, according to the developers blog, it only took him about 10 days to learn Ruby on Rails and develop this application which uses AJAX very extensively. Sounds like Ruby on Rails is really a good choice for rapid web development. Maybe I should kick myself into learning it finally (…if I only had time!).
A few thoughts on how the whole Web 2.0
hype thing might interfere with search engines.
After looking into all the new possibilites that come up with AJAX I came to think a bit about how Searchengines index pages and how the semantic web might be influenced by those new technologies. If people use AJAX more and more (which I hope they do) to create less web-like user interfaces which update information dynamically, searchengines won’t be able to get a view of all the information available on a specific website.
The possible solution I came up with might be something like a mashup between robots.txt and webservices. If a web aplication could offer a webservice for search robots that spits out XML rendered content of the information available on the page (behind the scenes in the database) the searchengine could easily index it and map it’s context, available in the XML structure, to the content. Another advantage would be that the sites could determine exactly which information should be found by searchengines and which should only remain on their site.
One offspring of this concept would be that services like the UDDI could be build up, that will be searched by the search robots, thus making it very easy to promote websites in a very descriptive manner. (Remind me to start such a directory website, when the concept kicks off. So I can charge customers for being listed and make loads of money 🙂 )
