Anyone noticed this?

Certian pages getting PR Zero'd?

[Rollo]

I have a site with about 30 PR 7 pages and I noticed that two of them recently got PR 0'd where they had previously been PR7. The rest of the site seems to be unefected (thankfully). These two pages were link exchange related pages with little content.

This also happened to another site on ALL foreign langauge translations (Italian, Portuguese, Spanish, French and German) which were PR 0'd, but the rest of the site (i.e. the English) is fine... (once again, thankfully).

Anyone else have a similar experience?
