Yes i think you should become a member of Google+, now it is very common network website and you can use it for company knowledge and visitors source for your enterprise.
+1 for your joining G+. The service is really promising in terms of its development as an innovative social networking tool. Btw, as far as I'm informed, they've already eliminated the age restrictions in terms of membership.
Most definitely join Google+! It gives a much more professional way of social networking. Rather than sharing your information with people who choose to share theirs, you can choose to share your information or not, even if you accept to view others' information.
We use different Google products everyday and that's really simplifies our life. we don't have to make plenty of accs, everything is by google. it's #1 and it's true. So, joining G+ will just make your life a bit easier. i think, it's worth joining G+!
Like to tall you that G+ is really very nice. Today I use it and create a page on G+...... It is easy and awesome service for we all.
if you're considering to promote your website or your clients' then you should join Google+ because it helps a lot for SEO....
Of course you should do it earlier. everybody wants to go with latest technology and you are still awaiting for someones response that you should go with it or not?
I'm on twitter and facebook, and that suits me fine, Google is far too late with their own social network, why they didnt just try and relaunch Orkut in the countries that didn't take to it I don't know...one area Google has failed I feel and doesn't want any other brand such as FB and twitter to elevate themselves to Google's status
If you are interested in social media websites then you can surely join it. And if you are already on facebook then you will feel bad on google+ because facebook is better than google +.
