I love tags and feeds.
For the last 15 years almost every technology project I have been involved with was somehow related to tags and feeds (I started with feeds in 1998, then added tags sometime in 2001).
The fact is that a feed aggregator is an incredibly powerful concept, and that using tags to organize and create views in aggregated contents is a great way of managing information. There are many tools you can use to create feeds. There are not that many that allow you to manage feeds, that’s why I find aggregators interesting, especially when used to power a content management system.
I’m now working on my 3rd aggregator, hoping to avoid the mistakes of the past and trying to make brand new mistakes which will teach us something. It looks like it’s the right time: with GReader closing down people are talking about feeds again, and tags seem to be back on the map too (with still a few pretty big issues to solve).
And there might even be a little conference on RSS!
