Although a post going back to last year, it’s a good article from Ellie Mirman from HubSpot dispelling some of the myths of getting involved in social media. There’s a lot of sound advice here.
“There are a lot of so-called “social media experts” out there. Dishing out advice, sometimes based on limited experiences, and sometimes based on nothing at all. Even the true social media experts sometimes share some misguided advice based on their beliefs and experiences. So with all this bad advice floating around the web, how do you distinguish between what you should — and shouldn’t — believe?
Have no fear! We’re here to share some of the worst pieces of social media advice we’ve seen to debunk all those misguided “best practices” and steer you in the right direction toward social media marketing truth and justice.

30 Terrible Pieces of Social Media Advice You Should Ignore
1) You need to be on every single social network.
Especially if you have limited time and resources, don’t spread yourself too thin by trying to maintain an active presence on every single social media site. Research and learn about the makeup of the audience that populates each social network so you can figure out where you should focus. If your audience isn’t there, don’t waste your time. And as new social networks pop up (as they do all the time), feel free to experiment with them, but be ready to let them go if they don’t work for you, and let your analytics be your guide. At HubSpot, we’ve tried pretty much every social network that’s popped up, but some have fallen by the wayside, and we’ve focused our efforts on the networks that continue to generate results for our marketing. Not sure where to start? LinkedIn, Facebook, and Twitter are safe bets. They have huge audiences that span many demographics and industries.
