Every once in a while I hear about a company making sure their executives aren’t active on their competitors sites (think Twitter, Instagram, Facebook, Google). I think this is a terrible mistake.
If anything, you should be the most active user of your competitors’ products. You should understand what works, what doesn’t, and how you can continue to make your product better than theirs.
You can’t truly comprehend your competitor unless you are a user of their product. This doesn’t mean you need to publicly blast out promotion for your competitor’s product, but make sure you use it like a typical user would. One additional user is not going to make a difference for your competitor, but it will make a difference for your business.
