I am annoyed by RSS Aggregators!
They do not have the functionality I would expect from the word Aggregation.
What I want is to be able to select multiple feeds and have them visible in a single view.
i.e.“One feed to rule them all and in the darkness bind them”
Most Aggregators seem to just act as simple newsfeed clients.
Each feed has its own seperate inferface/page. This is crap.
What I would like to see is an Aggregator that allows you to mix and match your feeds.
I would like the feeds to be considered just data sources and then be allowed to filter on those sources to create new feeds.
These data sources can be added to, or removed from, the filters and keywords [or tags] can also be added to these filters such that you can then filter out the interesting information from the feeds.
For instance. Say I have BoingBoing, SlashDot, Engadget and Gizmodo as my feed pool, these will act as a source, but I then set up a filter on Apple and “Mac OS X” this should produce a new feed that is both an agregation of the four source feeds, but also filtered to give me only information on apple products and anything Mac OS X.
I could then use this new aggregate feed itself as a source feed. [hmm, could get a bit recursive!]
This is the kind of service I want.
You can, kind of, already do this to some extent using google… Well if you know your URLs.
http://blogsearch.google.com/blogsearch_feeds? &c2coff=1 &q=Apple+OR+%22Mac+OS+X%22+blogurl:slashdot.org &ie=utf-8 &num=10 &output=atom
[Of course remove the returns]
This will filter out all posts on slashdot that are not related to apple.
You can change the above parameters to give you different results.
For instance, the output parameter can also be rss.
Unfortunately you can only do such filtering on one blog or ALL blogs.
Not a subset defined by you. 😦
If this was possible then I would use google as my ‘basic’ Aggregation service, and then use a normal rss reader to read it.
Hmm. Perhaps a little featurette to be added by google?
// edit: Google does have a reader called, strangely enough, Reader. All they need to do is implemented content filtering and true aggregation and they will be all set!
