What features of Google Reader are most useful?
I love that you can get Google Alerts feeds in Google Reader.
I love that you can export and import OPML.
I love that you can get output feeds via public folders.
I hate that there are no filters.
My ideal solution would be to merge FeedBurner into Google Reader, and then mashup Yahoo! Pipes inside Google Reader.
– Why is there no plug and play database as a service for web feeds?
The other thing is that there is no plug and play DBaaS expressly for web feeds; I would love to be able to accumulate custom DBs from feed items, and then be able to easily query them via API with feed output.
