Ask HN: How can I make Hacker Newsletter better?

Last year I doubled the subscriber count for Hacker Newsletter[0] to 14,000 and my goal for 2013 is to double it again. To accomplish that, I have several ideas I'm working on, but thought I would check here as well since the newsletter exists because of this community.

If you already are a subscriber, I would love to know how I could make it better and if you're not, is there anything I could do that would make you sign-up and check it out?

Thanks!

it seems that you yourself read articles that are in the email. so i think writing just a few lines that describes every link is a good idea. Dave Pell is doing a good job about this in NextDraft.

also points and number of comments are important things to be included in email, but they may clutter it. personally i prefer them to be there.

and the classics part is really good ;)

What is it written in/how does it work code-wise? Also, would you run another version/flavor for a subtopic like visualization?

I wrote a custom Ruby/Sinatra app that helps me build it out each week and use that to hand-pick each article. The app scraps HN (although I'm about to convert it over to using the hnsearch api I think) and allows me to filter all the links each week in various ways. I then use MailChimp (and it's great api) to send it out each Friday.

I'm working on making the app more generic in terms of the source and I have a couple other topics that I want to do, but just haven't had the time to finish yet. Look for another one in a month or so though.

I just signed up, and I gotta give it to you that the look and layout of your site is very very nice :) Everything is very clear and from my five minutes of browsing the archives I cant personally find a single thing to criticize.

I read in other comments here that it´d be great to have a summary for each link. But I imagine that would be tedious and time consuming. Personally I think the titles of the links do just fine :)
