I wouldn't be at all surprised if they credited wheel's citation with the link juice it deserved despite the no-follow.
but it's also a way of telling them nobody paid for this thing
if I pay someone for a link, I'd require it NOT nofollowed. Free links are nofollow, paid links are not.
Nofollow has screwed the link graph even for regular citation type links.
I agree. Don't know anyone who'd pay for a link and be happy with that link having a nofollow.
Practically, if I pay someone for a link, I'd require it NOT nofollowed. Free links are nofollow, paid links are not. Opposite of what was intended actually.
How does Google handle nofollowed links?
In general, we don't follow them. This means that Google does not transfer PageRank or anchor text across these links. Essentially, using nofollow causes us to drop the target links from our overall graph of the web.
it seems strange a site would give a citation but add a nofollow.
