The rest I agree with.

I can reasonably easily get a few thousand hits out of a combination of these sites, even with a very young blog. Much more with an older blog. All you have to do is write something insightful, bite-size, funny, well written, appealing, with a great headline, and get your friends to upvote you. That works on Reddit. There's no guarantee for any particular article to make it, but over a period of a couple of months any decent writer should be able to make it.

(I'm speaking from experience btw)

Digg is a pain in the ass in that respect. The volumes of "diggs" required to even make a blip are so huge that you'll only make it there if either you've totally gamed it (like that guy who posted that article about it recently), or if you've made it through somewhere else and you're dugg as a side effect. I stopped bothering with it because I kept hearing that the quality of the traffic is also very low anyway (very high bounce rates).

Reddit and HN, however, are relatively easy to promote to, and if you get really picked up very well on reddit (which should happen with 1 article every few months if you're good and write reasonably often), it'll spread to other places too. Articles that succeed only on HN don't seem to spread around too much, however.

The best place so far, though, was Slashdot. Get yourself slashdotted (on their main page), and you can expect 100k+ hits from it, and many links from blogs, and probably you'll get reddited, delicious'ed, dugg, etc, soon after. Be sure that your server is ready to handle it... It's a complete lottery - an actual editor has to decide whether to push your article - but if you win it, it's worth it - so submit there when you have good slashdot content, it's free and might bring you untold amounts of geeky traffic!

Bear in mind also that none of these methods guarantee anything - not even traffic, and definitely no guarantee that people will stick around. But they're not overly hard to achieve if you're a decent writer and have something reasonably interesting to say (those are the hard bits, really).

Definitely I would recommend just running a blog on Wordpress.com or TypePad or blogspot. Some service that can withstand the heat of any big press releases. Just in case. You can spend a few bucks to make it look like a subdomain of your main site anyway. Blogging can net you some organic search traffic too.

1) Hacker News

2) Reddit

3) Stumble Upon

I think that comes from submitting your start-up as opposed to submitting a blog post about your start-up. Each submission has a small chance of success (especially early submissions), but if you write and submit often, your chances increase, as does your skill in how to submit successfully.

If you only have one shot at it, though, then yes, it's a waste of time.

If your product is something that needs to be marketed to the blog-reading masses, I'd say that having a decent writer on board is roughly as important as having a decent salesperson would be for an enterprise-facing start-up.

If you can't write, better get started. Practice makes perfect. You don't need to be an amazing writer to write a successful blog, imho. You just need to be somewhat articulate and have interesting things to say (which, as an entrepreneur, shouldn't be too hard?).

As a side-note, if anyone knows of any way to reach the construction industry that would be as effective as TechCrunch is for geeks, please let me know :-)
