I'll be 100% honest.
I can genuinely see both sides of the coin, and unlike most on this thread I have been responsible for both sides as well, so I can say with total certainty that I really dont think there is a right answer, its that classic "you can't please all the people" scenario.
Before David puts his waders on to get across the River of Hurt he has made for himself and poke me with his anusol applicator stick
he should perhaps realise that Im not entirely sure I know myself how I would want the commentary to be for these events and am as guilty as Ian et al for similar things in my time, whilst also sometimes thinking "its getting a bit much now boys" with some of the comments.
What I do know is that it fucking hard to do that job, for that long and keep an audience entertained, and I never had a livestream audience to worry about who I had no idea of their connection to the teams, level of interest or experience of drifting etc.
If you know the audience is inexperienced then you can fill with trying to teach them the basics of drifting, the rules and details of whats going on - experienced audiences find this boring, irritating and doesn't engage the majority of those especially at a BDC event who are usually directly connected with competitors.
If you pitch to that local audience then there may also be things that they can see that the cameras dont and as such all reference gets lost for the home audience. Also pitching at that more knowledgeable and "connected" local crowd inevitably leads the new listener or home listener to wonder why they are just listening to a stream on "in-jokes" and nicknames/banter etc which again leaves a large chunk of people disenfranchised.
Add to this the fact that you want commentators to know what they are talking about which like almost every other sport that has commentary inevitably leads to using current or former participants to help do that commentary. This immediately brings you bias, referencing to past experience of the commentator and a degree of in-house ribbing, all pundits do it, but then its also the biggest plus point of having them - FOR THEIR INSIGHTS. So again a two sided coin
Drifting is primarily a younger persons sport like most extreme style stuff as its dangerous, wastes money and is usually something people grow out of for "life reasons", sure theres a few old farts like me still hanging about, or some bloke called Mollisaan for example, but theres 10 more who no longer are around to prove my point. This results in age related opinions differing, I might like more factual stuff, perhaps like you, but youngsters often want 3 seconds of info, 10 seconds of bollox and 30 seconds of comedy, so again for the majority the lads have probably got it right.
Theres loads more arguments for and against, I actually do agree that if it was slightly more professional it may appeal to a wider audience more, but I am not sure drifting will ever be that wide, frankly I think that restriction would lose some of the spontaneity of what the guys do and we would all be poorer as a result.
I have probably made judging calls with bias, sworn on mic and generally been totally "frail human" while trying to do the very thing you want done, so I can say that its such a tough job I think you should just be happy that any poor fucker is prepared to put themselves in that spot and do what they do, so fair play to all of em !!!
So to sum up.........................STFU Homo !!!
