I wouldn't submit anything of mine to HN out of fear that the traffic might bring down my site (Webfaction hosted Django/Nginx blog)... and also because at the moment I wouldn't have anything to gain from the traffic besides a temporary ego boost.
EDIT: Speaking of which, is there a service out there that can test how much load your site can handle at one time?
It's sad that you would submit something only if you can gain something and not to help the community.
BTW First results in google for "website load testing": http://loadimpact.com/
For example you could try this service out and write a post about your experience and submit it to HN so you could help the community with useful information.
Thanks for the suggestion. I will try it out and maybe find other services I can compare this one with.
My experience with programming/product launching is also so junior/non-existent that I doubt anyone on HN would be interested in hearing about it. So the only other reason I might post (at this time at least) is if I were selling something (and I'm not). I was just being honest about what I feel I can contribute to HN at this time. Which is very little, hence why I stick to merely commenting.
