The types and quality of stories on HN are like the tides; it regularly varies. One of the goals for HN is to have a good, balanced mix of interesting stories. Due to voting, populist stuff will surface, but HN still has an appreciation for heavy-weight, time-intensive articles.

Some truly great stories get few, if any, comments. If a post requires effort or specialized knowledge to even ask good questions, then there isn't much discussion. This happens a lot when academic papers are posted since reading a paper might require a multi-hour investment, but even when there is little discussion, it's good to have heavy articles submitted. They balance out the other stuff.

If you find something great-but-overlooked in the /newest queue, then send an email to hn@ycombinator.com asking for a repost request to be sent to the original submitter. That's what I did with this article, but Dan (dang) asked me to repost it myself. Neither 'ingve' nor I care who gets the credit/karma, but a lot of people want great articles to get attention on HN.

HN is what we make it.

This was posted once before by HN user 'ingve' but didn't get much attention [1]. Though the most recent and largest (39 pages) JFP paper, "Systematic Abstraction of Abstract Machines", is probably the best version to read, the earlier "Abstracting Abstract Machines" may also be helpful. There's also a CACM highlight version of "Abstracting Abstract Machines" that's only 8 pages. All of these papers are available.

- "Systematic Abstraction of Abstract Machines" from JFP 2012 (39 pages)

http://arxiv.org/abs/1107.3539

- "Abstracting Abstract Machines" from ACM ICFP, 2010, (12 pages)

http://arxiv.org/abs/1007.4446

- "Abstracting Abstract Machines" from CACM highlight 2011 (8 pages)

If you want feedback on your project or startup, then you are much better off doing a "Show HN" post so it is listed under "show" in the main top menu. The rules for doing a "Show HN" post are here:

https://news.ycombinator.com/showhn.html

If we're lucky, a moderator will notice and change the title of this submission for you (i.e. turning it into a "Show HN" post).

The first thing I noticed when reading your site is this:

"There are also multiple premium features users can access after upgrading their account (a one-time fee of $10 Canadian dollars)"

A one-time fee does not seem reasonable or viable for a business. For the long term sustainability of your startup, use an annual fee.

Also, I did not see links to either your privacy policy or your terms of use. At least some people will be concerned about copyright issues on their photos, and how/where/when your site is able to use or promote them.

Mat, text submissions are at a disadvantage in sorting compared to url submissions, so you're much better off submitting the businessinsider url. Also, titles should be descriptive, and a title of just "YO" is an attempt to make it stand out, which is against the site guidelines. If you still can, you're better off deleting this submission and creating a new one by submitting the BI url.

https://news.ycombinator.com/newsguidelines.html

"Please don't do things to make titles stand out, like using uppercase or exclamation points, or adding a parenthetical remark saying how great an article is. It's implicit in submitting something that you think it's important."

It's an interesting question, but I don't know of any books that specialize on the mistakes of founders/projects, save for the Mythical Man Month [1] by Fred Brooks. HN does get a lot of "X is closing down" submissions, and some of them give interesting reasons for why the company didn't make it.

On a general level, there are usually more ways to make fatal mistakes than there are ways to make things successful.

Surveillance by a nation-state is troubling problem, but surveillance by the populace is an equally troubling problem.
