I think it would be better to link to https://douban.com .
If rank by semrush is considered useful, maybe putting it inside parentheses or moving to comment area would be better.

Hi @kentslaney, thanks for the the useful edits in this PR. We think the semrush data is not really reliable for PRC based services, is there a better source for stats? If not, a direct link to douban.com or maybe a link to wikipedia's page could be ok too.

[kentslaney]

How about this link instead? I wanted to link to site usage data rather than the home page since the volume of requests supported seems more relevant for libmc users than the content of the site.

I insist that https://douban.com would be better.
If an about page is preferred, how about https://douban.com/about?

I dont agree with https://jobs.douban.com/about/.
It is not relevant to a hiring jobs page.

I agree with site usage data,
but site usage data should not appear in a more primary position than https://douban.com.

@kentslaney maybe two links can work better than a link on jobs page, like: powering all web traffic on _douban.com _ (_page on wikipedia in English_)

[kentslaney]

Ok, I did a link to the main page and another to the english wiki. It was a little weird having a link with the text douban.com not going to the home page anyway.
