Does the Arc/Lisp process only handle one request at a time? If it handles multiple requests at once how do you keep the writes atomic?

Actually, if they were innovating, or planning to innovate, that would be something. But they're not innovating (or rather, nothing in the article led me to believe that they are). They're desperately trying to find a way to map their business from the old media (Television) to new one (the Internet). The new transcends the old. What worked well on one isn't necessarily going to work well on the other, and unless they "get" this sometime between now and launch, they'll fail.

For the time being, I'd settle for just converting newlines to br's. Adding hyperlinks before there's solid infrastructure for dealing with spam would be a mistake. I'll be surprised if more than few days go by before spam shows up, even without hyperlinks.

Spam actually showed up the first day. Fortunately we already had good tools for dealing with it.

What type of spam do you get and how do you handle it?

I know this is an early version and things are still a bit rough, but just for the record: 1) The number beside my user name (top of the page) is a bit confusing. At first I thought maybe it meant I had some sort of message waiting to be read, or perhaps that I'd made one comment, which didn't make sense because I'd just created the account. Perhaps a label before the number would clear things up: (karma: 1). 2) I didn't realize at first that the arrows were used for voting. The main page (http://news.ycombinator.com/) had only "up" arrows. I figured they were used to collapse/expand additional content, so I ended up inadvertently trying to vote for several arbitrary items (I hadn't created an account yet, so the votes didn't count - I don't think). Once I saw the "up" and "down" arrows together I got their purpose. Perhaps, instead of removing one (or both) of the arrows you could simply display a ghosted one? Or perhaps replace the arrows with thumb up/down icons? 3) "7 points by pg 1 hour ago | 7 comments" reads like you (pg) added 7 points an hour ago. Is this meant instead: "7 points | by pg | 1 hour ago | 7 comments"? New feature: Why not combine the scoring with Flickr like tags.

4) Tell me there's a character limit, and what that limit is :) New feature: Why not combine the scoring with Flickr like tags. Instead of just being limited to increasing/decreasing an items karma, give me the option of increasing/decreasing tags, and the ability to add a new tags of my own which others could then vote on. This would probably be a good feature for Reddit as well. They could do away with the handful of subreddits they have and use this tagging scheme instead.

I think this is a great idea. It would let things like slashdot's "funny" and "insightful" happen organically. I've been toying with doing something similar for a political blog for a while.

Have you seen slashdot lately? They've got some sort of freeform tagging feature and it ain't working so hot.

Here's one: get newlines working. Either allow <br /> elements or translate the newline before applying the comment. It'll make the comments a lot more readable. I know it can be abused, but I don't think that's really a worry in this forum. You can always turn it back off later, right?

Nitpick. I noticed this is working now when you type two newlines, but when it's just one newline it translates into a space. I'm probably the only one who cares though...

Oh! I always thought it was a deliberate filter against lists of items taking too much vertical space.
