While PageRank might not be all that important to your site, it is important how your site is perceived by others. PR used to be _the_ way to measure the value of a site and that kinda stuck.

> I’ve seen folks spend thousands of dollars per month on links or advertising on a site simply because ‘the site has a great PageRank’.

Me too, so if you are a site that thrives on advertising or link revenue, PageRank remains very important.

Avvo.com said that when their PageRank rises, so do the number of business development calls. Even when PR and business dev calls are not correlated, the perception is still very real.

For larger sites having a higher PageRank also means deeper crawls, longer crawls and faster recrawls (I've heard it influence rich snippets and sitelinks too.). Not something to measure like it is the holy grail of marketing, but it is something to keep an eye out for, even if it just to check if you are not ranked 0 (which could mean a serious problem).

I wouldn't put my money where my mouth is, if PageRank doesn't matter, I still prefer links from higher PageRank domains. PageRank might be dead, it is not buried yet.
