Think about this please. Some may say that all bloggers can help each other to improve their blogs, but my experience is that following bad advice can cripple your blog's ability to earn a decent page rank and for your to earn any authority in your niche. So I'm thumbs down when it comes to what I refer to as cattle calls.
In essence, when making a cattle call what you are asking is for
(1) the opinions and advice from other bloggers, who make or may not have successful blogs, when their feedback could be of dubious value;
(2) the opinions and advice experienced bloggers, who do have successful blogs, including those who are paid consultants to work free of charge for you.
The Community Pool is for those of you looking for feedback, whether on post ideas, writing, blog design and layout, or anything else. There's a new thread every Sunday. Here's the latest one http://dailypost.wordpress.com/2014/08/03/community-pool-75/
If you want professional advice then my advice is hire a consultant and pay them for it. Code Poet is a directory of WordPress professionals, web designers, and developers brought to you by Automattic, the company behind WordPress.com http://directory.codepoet.com/
