The below article from Stepcase Lifehack really resonated with me from a link building/publicity perspective.
In my earlier years, I often felt the need to sign up and create accounts every time a new social network or related venue/tool appeared. It’s easy to get caught up in it all. Then, as time went by and those same hot brand new venues became ghost towns and/or vanished, I realized they weren’t quite as crucial to my client link building efforts as I initially thought. Go back even further, and the same addiction applied to search engines. I think I submitted a few thousand URLs to Excite once upon a time…The lesson for me has been that there will always be something new, bigger, brighter, cooler, and none of them matter. What matters is meritorious content, influencer identification, and topical merit based link seeking based on one to one interactions.
To bring this around to something tangible, if you have truly outstanding and useful content, you don’t have to have a perfect understanding of how to get links from every single communication tool or social network. Learn a bit about a few of them, like Twitter, delicious, digg, reddit, and stumbleupon, and then…at most all you’ll need is a content publicist (aka link developer/builder) to show you how to get the link waves started.
