The Underwhelmers:
Having social media accounts that aren't managed on a regular basis can actually work against your company. It looks like you just don't care about business or your customers and can turn off potential customers. Even if you do put a lot of information out when you do decide to update your status's, spurts of information won't be enough to keep people coming back.
The Overwhelmers:
Some companies take the approach that the more advertising and publicity you have the better! But as the old adage goes, everything in moderation. Over tweeting or over updating your Facebook can just bombard your followers with information and make them not want to have you cluttering their feeds. People don't want to have to hear about how great your company is every second of the day.
So what do you do? The best solution for managing your social media is to create a schedule for how often it will be checked and updated. If you have set times you will be much more likely to do it consistently and therefore reach the most consumers.
