Drops aren't really necessary to show. Only a hardcore buggy person (such as myself) would care about them at all. It would help, though, if the commentators let us know when someone failed drops (which I think they did for ROTC, but not SigEp). As I said before, 95% of drops don't matter at all, and definitely don't need to be shown. The only times I would think that they would want to be seen in general are for the teams expected to be in the Top 5. If your team completes a flawless run, and you're in the chute celebrating, the worst thing would be to find out much later in the day that your team failed drops (or, alternatively, if you're just outside of a trophy spot, your whole team gets to have a little party at another team's failure). Drops would also be nice to see for teams that seemed to have steering/mechanical problems during the race (see: ROTC), but that is a) Rare, and b) Unpredictable. In short, commentators telling people that drops were passed/failed would probably be enough (or, as someone suggested in a chat, you could put up a little green dot on the screen for passed drops or red for failed drops, but since it's not always clear who passed, it's probably easier for commentators to just state what they saw).
As for the commentators, I thought they were fine. Will has got the general hang of things and clearly does research beforehand, which is nice to see. I may have generally disagreed with a couple of things that were said by a couple of the buggy alums who were on the air, but they're entitled to state their opinions (even if those are wrong). I do kinda miss having a voice down in the chute though.
One final thing...On cmubuggy this year, there was an "Ask The Broadcasters" feature, but I'm not sure if/how that worked. A couple of suggestions that I know were sent in regarded the Fringe A pushbar DQ replay, and a leaderboard error regarding SDC B and Fringe B in Women's finals. Those were both corrected. However, some of the things sent in, such as questions about the SigEp Fire Safety DQ, or a note I sent in about this being AEPi's first finals ever, went unmentioned. So I don't know if that feature was working, or who was getting it. I kinda got the feeling during the broadcast that cmuTV was getting those requests, but the WRCT folks were not. It's also possible that cmuTV caught the same things that us watching at home did (like the Fringe A pushbar), and showed replays completely unrelated to that feature on the site. But I think that's a nice feature to have and maybe it could be better incorporated next year.
