I've built a few links on 50 EDU / GOV websites. 1 of them has PR 8, 3 of them have PR 7, 8 of them PR6,7 of them PR5,12 of them PR4,8 of them PR3, 1 of them PR2, 6 of them PR1, 10 of them PR0. My website has PR3 and is on first page of Google/Yahoo/Bing for a few keywords that I like How long will it take to notice a difference in PR or domain authority? (Don't tell me that PR has no value now, I know it but it is a 'fashion' thing).So you say that DOMAIN Authority isn't an important factor?

No-one can tell you exactly when the PR will be updated, since that is fully under google's control. Anyway, as Matt Cutts asserts, .edu and .gov backlinks have no more weight than any other extension.I also find this quote on the web:Are .gov and .edu back links still considered more link juice than  the common back link?This is a common misconception--you don't get any PageRank boost from  having an .edu link or .gov link automatically. Hah John, I beat you  to it! If you get an .edu link and no one is linking to that .edu  page, you're not going to get any PageRank at all because that .edu  page doesn't have any PageRank. Matt Cutts
