Niche and regional directories are becoming more important. It is true there are a lot of general directories where the owner's goals were short term profits, and lacking in long term vision. But on the other hand, there are niche directories like
MMA Station that clearly have goals, serve their readership, and are in it for the long term.
It is true that many directories lacking a vision have already been penalized or the owners are AWOL. They may have already "died". The same thing could be said about most any type of business or website. Right now, if you are going to start a general directory, you need a good plan to succeed, as there are many others like you. If you are going to start a niche or regional directory, there are lots of opportunities open to you right now.
And some of the niche and regional directories will do well, and some not so well. I've seen some interesting ideas such as:
Worst Food Ever
Gate UK
City Journalist
It's good to see some refreshing ideas in the industry, and I'm sure we can look forward to many more in the times to come.
