The biggest way to lose influence and followers is by senseless linking/syncing apps & allowing them to show up in feeds. Keep in mind, checking in on foursquare every 10 minutes & pushing it to WordPress doesn’t make you a blogger. It’s also very inconsiderate. Save it for Twitter or Facebook where it makes more sense.
I can think of several others .. make sure to actually check your pressed blogs every once in awhile, I have no doubt several folks will be mortified.
