Considering the captcha it actually takes 3 clicks to launch
More like ten.
Six for the captcha choices, one to submit the captcha, one to pick the server type, one to submit and get a "Server capacity reached, please try again later", and finally one to close the browser tab.
Fyi, it doesn't have to be a $500/mo server permanently either. Depending on where your hosting the backend, you could scale it up temporarily and then scale it back down when things quiet down. $500/mo is approx $16/day which could be well worth it for a day while enjoying an HN-driven bump.
