I can't separately use SNS sites

Facebook, Twitter, Google+.

Needless to say, these are major online SNS sites.

In addition to these, there are other big SNS sites in Japan. Mixi is an example.

There are so many SNS that I can’t easily keep track of them all.

Some friends mainly use Twitter and others mainly use Facebook.

When I have some things I want to share(photos, messages, quotes, etc) I have to post them to each site individually!

There are tools which enables you to post to multiple SNSs at the same time, though I still feel annoyed with the situation.

I wonder how other people handle these services.
