Google+1 is not helpful for search engine ranking, so I haven't tried it. Secondly, it helps to popular your page/site within your contacts.
I think it's too early to tell what +1 will do. I'm worried it will be too easy to game the system, and also that more niche sites might get swamped out by bigger sites that everyone "likes".
Yes !!! really working good for me, but only one thing is some unknown persons are following me without my permission ....
Interesting! I would like to ask how is Google+1 not helpful for engines? BTW thanks for all the response.
In google+ there are lot of features included.. if you started once then you'll surely not leave. try it now..
