ShareThis & Plurk

I noticed today [I don’t know if this feature is new or old] that in any Plurk’s page appears a ShareThis link to add the selected link to different Social Bookmarking sites

Great thing – now we can easily add our favorite plurks to our Social Bookmarking accounts.

What do you think about this feature? [if it’s an old one sorry, but I rarely use the Plurk page]
