Google groups and Page Rank

Why doesn't Google calulate PR using links from Google Groups

[crisscross]

Does anyone know the answer to this? It seems strange that Page Rank does not include these links, especially considering Google's recent purchase of the blogging company.

He he, funny that title. Reading your post, I found it more in line with my thoughts on the matter.

Though, with a more 'controversial' title like the one you have now, I'd say you might end up with a better CTR for your thread.

And thus potentially higher ROI, if you consider ROI a combination of intellectually stimulating banter and pageviews. he he.

yep jomaxx has got it, but not necessarilly limited to those kind of sites. If google started giving Pr to usenet/news groups it would crack under the strain of everybody going back to the old lady...

Surely Google could devise an anti-porn system.

Newsgroups are the #2 place for spam, #1 is in your mailbox ;) No matter how many good threads exist on the groups theres always someone plugging a URL here and there and signiture tags and other things. Because newsgroups posts are commonly faked/forged and the origionation is vauge in many sences compared to a web site sitting on a server with a IP address assigned to it I think it would be hard to give normal credibility to it. Plus google.groups is just web interface to newsgroups, you dont see google indexing your e-mails ;)

Thanks for the replies. I should have thought of those answers before I posted :(

No worries, I didn't think of them until I started typing and when I did started typing reasons became valid :P

Google groups can be nice for regular plain vanilla link related traffic.
As a resultant it can lead to nice real links.

I would not be suprised if, to a very small extent, Google would find a way of using the number of links towards your site in the normal algo (not necessarily Pagerank), whilst disregarding signings.

It may not count for PR, but don't you think GoogleBot does follow links found in Usenet? Tested and confirmed a year ago, but I've not heard of anyone testing it recently.
