To use google plus comments on your site all you need to do is insert the following code on the page where you want the comments to appear
url should be the full url to the page, then any comments in google plus with this url will appear to any user who can see them (ie public comments or those from people in the viewers circles).
If you have a gmail account, you get a google plus account with it, many of end of with several of each. For mail this is usually what you want but for plus with it’s circles you usually just want one account and to split post by circle. Fortunately there is a way to redirect one account to another.
This way anyone looking for you at the account you don’t really use or looking you up via an alternate email gets redirected to your active account.
I have just got the new gphone, the G1 which is a collaborative venture: google provide the OS, HTC make the hardware, T-Mobile provide the netwwork, and loads of software is written by many people - and made available via Google marketplace.
While a few things feel a little beta still; on the whole it all hangs together very well indeed.
