I asked on Twitter:
"Looking for an automatic site map creation tool for content audits. Recommendations? Is Powermapper any good?"
Here are your answers:
@davewpetersen: WinWSD ia brute force tool & SortSite (more tech audit oriented)
@amyk1203: powermapper is a good for starting an inventory. Support response is quick too.
@logorrhoea: I use iGooMap (Mac only, I think). Or try Integrity (also Mac, donationware, I think).
@leannebyrom: Powermapper works really well for site mapping
@doriantaylor: there is also SiteOrbiter
@boonerang: I rely on Xenu to get the crawl data right then port to MindManager or other tools
@guerillagirl_ pointed to the Omnigraffle Site Map generator
@carlrc Let me know if you find one. I use integrity to crawl links and then edit down that data in excel
