I've gone through old Hacker News links and tagged them. Also, every hour, new HN posts are synced to Archfinch.

Only posts with at least 10 points are shown, and automatic tagging uses the Delicious API (no autotagging involved). Users can also tag things manually (and they do).

You can follow and block specific tags, e.g. you can follow linux, python and math and block techcrunch, facebook and iphone.

Some highlights:

http://archfinch.com/tags/ycstartup - all YC company news

http://archfinch.com/tags/hn/videos - videos that appear on HN (automatically embedded)

http://archfinch.com/tags/hn/pics - same as above, except pics

http://archfinch.com/tags/programming/history/lisp - an example of how deep the tags go

Bonus: some stories have wiki-style summaries

However, perhaps I could add tagging suggestions based on content extraction / keywords.

Much good feedback there, it would be interesting to see a report of how much of that was taken up and integrated, how much was tested, and how much was ignored.

Instead, this submission is a repeat of this one from 4 days ago:

I did, however, ignore some feedback. Well not really ignore, I listen to every piece of advice I get, but I can't implement every feature request. Plus often advice is contradictory with other advice :)

For example, people tell me to get rid of 1-5 ratings and just do 'like/dislike'. I won't do that because there is a chasm between 'like' and 'love'.

I could write a detailed post on what exactly I took to heart and what I didn't do.

Regarding the repeat. The submission from 4 days ago didn't end up on the front page for some reason, even though from my observation it had the necessary upvotes (it had more upvotes than an older submission that was on the front page). I figured it won't hurt to resubmit, and it worked this time.

Thanks!

It's interesting how accurate the tags are and how much more information they give. I've been playing with them for a while and I can sit and browse for hours.

Great project though.

            for char in key:
                if ord(char) < 33 or ord(char) == 127:
                    raise Client.MemcachedKeyCharacterError(
                            "Control characters not allowed") ...

http://archfinch.com/rss/tags/programming/history/lisp - example tag rss

http://archfinch.com/rss/followed/drx - things followed by me

I plan to expand on that. Add other sources, perhaps add a way for people to add their own sources. RSS feeds filtered by topics would be cool.
