Count me among the relatively small group of people that thinks the loss of critics (sparked by the cost cutting and imminent closing of many newspapers) is a bad thing.
The arts needs good critical voices because those voices help consumers to make informed decisions about what to see (and avoid).
More importantly, a critic with a strong reputation is one of the vehicles I have seen (outside of audience word of mouth) that can convince someone to take a risk on an entire new artistic organization . . . or occasionally an entirely new art form.
Now I know in this tech advanced word we can replace your newspapers local critic with 100 online critics, but it may take a while (if ever) for any of those critics to develop the credibility need to drive a substantial audience in one direction or another.
Plus, losing critical voices tends to hurt smaller arts organizations that need a good, widely read, review to build audience for their work.
If I were those smaller orgs, I would start reaching out and supporting a few of the good online art critics. I'd make sure they came to my shows, I would give them info to report, maybe even buy an ad or two on their site (if they are into that sort of thing).
Trust me, you need a few of those critics with a small audience to become critics with a large audience . . . so don't be afraid to help them on their way.
