ReadWriteWeb author Richard MacManus asked a question on Google+ about whether or not people’s Twitter and Facebook usage has gone down since they started using Gooogle+. He received over 60 responses (more than he received on Facebook or Twitter) and it seems the census is a yes. It has significantly changed how much his followers are using the other social networks.

Some of the comments were:

• “it’s replaced Twitter totally for me… and will slowly replace Facebook as more friends get over here”
• “Living here now. I find it interesting because I’ve circled a lot of people who I don’t know and am gaining a wider perspective than on any other social network I’ve used before”
• “Don’t read twitter any more, Reduced facebook usage, increased use on Quora and Namesake”
• “Using all three, but am using FB and Twitter less than usual. Still trying to figure out exactly where G+ fits in (and wait for others to join)”

MacManus also gave 2 examples of Google+ power users who were previously avid Twitter users, and showed that  both have decreased their Twitter usage quite a bit.

Although he admits the survey was both unscientific and a little biased, it still makes you ask the question if Twitter and Facebook should be worried.

So, let’s do our own little survey here: Has Google+ decreased your Facebok and Twitter usage?
