This seems like something that will really spark discussion around the blogosphere and hopefully it’ll prevent some spammers from spamming, although I doubt it: what the hell do they care about the PR of a link that spammed into my blog? It’s either hard to even get something through (multi-layer antispam) and even if something slips through it’s just a matter of time until it’s deleted – I don’t think that the PR update will even recognize this?! And what about people posting interesting stuff in comments – doesn’t such a link have any value?
I’ll abstain from installing it atm though as I value links in comments, as long as they aren’t from some spam-bot, which should hopefully be caught anyway.
On another note: this might as well prove itself useful for linking to people without giving them credit, which was impossible so far.
