we are thinking about ways we can connect the two together in a tighter way to reduce some of this
as you point out, twitter and disqus are USV portfolio companies and we love using and supporting the products our portfolio companies make
On that... nail on the head.
It would be good if you could add a subtle addition of highlighting the things on the board in that a USV team member has contributed.
I think of VC firms as akin to a curator of interesting companies and opportunities, and that the sum of the portfolio reflects strongly the personal curation of the VCs. It'd be ace to see that shine through this new board.
The only conflict in that is whether you see this board as becoming more than USV, or giving an insight into USV. If the former than you'd be right to hesitate about highlighting the team's contributions, if the latter then do it already.
At least 25% of the time that I've clicked on a comments link, I've had to sit around (after the page has loaded!) waiting for Disqus to load the comments (what I actually came to see). Sometimes they don't even load at all and I have to refresh the page. I completely understand that you guys love supporting your portfolio companies, but it seems like this type of site isn't quite as well suited for Disqus.
Just my two cents. I'm excited to see how you guys improve on this, and other than these issues I think you've done a great job so far.
I think you could benefit more from automatically analyzing links from many sources than to implement a sharing service yourself.
but only time will tell if we are right about that
