If you don’t let your colleagues create communities on Google Currents, where else will they create them? Facebook? LinkedIn? Private email groups? All of these
situations are out of your control and also increase the risk of a data breach. The last thing you want is for an employee to share private company information in
public forum like Facebook. It’s much better to keep everything under your company’s control.
Bottom line: if you’re already using Google Workspace, Google Currents is a no-brainer. You’re already integrated into the Google ecosystem, so what’s one more tool, especially when it’s relatively easy to use? Go ahead and try it. If you don’t love it, you can always pull the plug.
If you don’t use Google products of any kind, you may be better off using another tool like Slack. Given that it’s only $6 per user per month, why not give it a try?
