Thanks for the feedback: Crocodoc (YC W10) has a new look and improved tools

I see a lot of YC startups create blogs on posterous rather then on their own domain. Is their a SEO reason/advantage to doing this? WOuldn't you want to send traffic directly to your site?

As a software engineer that doesn't really touch too many documents nowadays, I'm probably completely outside of your target demographic, but on my 3GHz Chrome 6/Ubuntu 10 box, the Flash document viewer was quite laggy. Scrolling the page up and down pegged one of my cores and the page content took 500ms or so to catch up to my pointer position.

When you pop up a comment, the hide and delete buttons are kind of confusing. The hide icon uses a 'minimize' analogy, which leads me to believe the 'x' icon means 'close.' On a related note, the popover doesn't really need to say 'comment,' it's pretty clear what it is - that space could be used to separate the hide and delete buttons.<p>You might try eliminating the word and having the hide button on the left (it seems comments always open anchored at the top left) and a delete button on the right. I would recommend changing the x (maybe make it red or a garbage can?) to make it more clearly signify 'delete.'

Looks great Ryan! It's certainly come a long way in the last couple years.

Nice job!<p>Little nit-pick - on the CrocDoc.com homepage you've got a space in "mark up" (crossed out) and then in the line below have it all as one word "markup".<p>Gramatically both should be "mark-up" with a hyphen - markup is used for actual code description . . .
