The Online Publishers' Association has released a new survey of at-work Internet use by daypart[ PDF].

The Internet is the best way to reach your audience while they're at work, and this study does a good job of showing the behavior of this audience.

I wish the study had spent less time wallowing in demographics, which are easy to collect but pretty meaningless, especially in this context. I also don't understand why they're looking at the at-work market as a consumer, rather than business, market.
