What are you looking for? Are you asking that Google+ automatically brings over all of your Twitter followers? Or automatically Circles everyone you follow? I don't think either of those would work out very accurately. I'm not sure what the barrier is that is keeping you from trying Google+, considering it's completely free, it's competitor is completely free, Google+'s character limit is far greater than any of its competitors (so you can post the same stuff)...

You literally can just try Google+ for a while, use it to create content, and if you don't like it you can go back to Twitter. They're not mutually exclusive. Google+ doesn't deactivate your Twitter account. It doesn't edit your hosts file to null route www.twitter.com. There are even browser plugins that let you post all your existing Twitter and Facebook content to Google+ retroactively, and let you post to both for future posts as well.

So... that doesn't seem like it's marketing's fault. I'm not sure what would be a barrier to entry to something that's completely free and demands literally nothing of you.
