No Firefox... no IE9... No idea what it even does... Am I the only one getting tired of clicking ShowHN links to sites with no clear vision or at least some kind of descriptive teaser, and minimal compatibility with the browsers out there on the market in the name of MVP? More dissapointing that it's due to a few CSS gliches...
Advice: If you are intending to ride the initial wave of eyeballs from HN, best to get those kinds of kinks worked out first. I'm hard pressed to find an example of an idea where pushing it out unfinished justified the loss of initial traffic.
Like some other commentors, if I go to a site that will not grab my attention in two of the three browsers that I use in that initial click, I'm never going to go back to it again.
