Let’s talk about tools for a minute…
Pinterest is a tool. Facebook is a tool. Twitter is a tool.
In terms of ANY social media site, connection site, pic-posting site etc… that’s all they are, tools. Nothing more, nothing less. The success of your business is NOT dependent on the use of these tools, although you should consider using the appropriate tools for your business.
In short, these are tools that connect you and your business with people who could potentially need what your business offers. You DO NOT have to use them all, you DO NOT have to use the “latest” one that came out (please ignore the tech geeks and their relentless Pinterest posts).
You ONLY have to use the tools that are appropriate for your business.
A photographer might use Pinterest to pin photos they took, and photos of others…
An artist might use Tumblr to show off their work, and save money on the cost of a website (although they should create their own website as soon as possible to avoid putting their eggs into one basket).
If you want a more robust set of tools connected to a host account, you might use Google Plus (again, don’t put your eggs in one basket like some geeks are suggesting).
And on, and on… decide which tools are best for your business (might only be one)… but you DO NOT have to use them all.
You don’t need a wheel changer to build a house.
