For the majority of bloggers, the posting sent out will be superficial and derivative. Surely, what your potential readers are looking for is something more in-depth and original, the result of your vast experience and expertise.
Either, you could spend 10 hours writing 10 bland blogs.
If the one 10-hour piece was that good it would be found... it would get retweeted... it would give you higher-quality attention from people who would want to engage with you.
If you are in the regular content game then the chances are you are competing with hundreds/thousands of others doing the same. You should be creating content that the others would find difficult to create. Content that lesser human beings are incapable of producing.
Recommending in-depth content flies in the face of web usability guidelines of ‘keep it short and sweet and simple’. Elite expert sites are an exception to the rule because you do not care about the 90% of readers who will never buy. You care about the 10% that want and need and deserve more from you and they want to see that you know your stuff.
Stop being so run-of-the-mill, boring and predictable. Spend the time demonstrating that you do know your stuff!
