I've seen several comments lately about the trend away from the browser and how RSS may contribute to this, it can be used in an email client etc. But the trend for Usenet was towards the browser, with eGroups and Deja. Likewise, despite lacking in features, people seem to like Bloglines, it is a browser based RSS aggregator and my money is on this model. Bloglines doesn't do what I want, perhaps Kinja will. My aggregator top ten wishlist items:

1. Search

2. Ability to pick a selection of blogs from a limited list of categories, not too many - prob like Google news.

3. Ability to do scoped search within these categories.

4. 'More like this' recommendations.

5. 'People who linked to this blog' button beneath selections.

6. 'People this blog links to' button beneath selctions (blogroll plus contextual)

7. Browseable list of blogs ranked alphabetically or by popularity or by rate of increase in popularity in addition to category lists above.

8. Ability to view other users’ public lists of blogs and to clone and modify their lists to add to mine.

9. OPML and javascript export of part or all of my list as a blogroll.

10. Installable browser component that takes my list and makes it like a bookmark list, but with one key difference, it shows the number of new items in parentheses next to the bookmark.

Overall I want something that looks like iTunes Music Store but for blogs.
