Hi Pelf,
I appreciate your comments but am not entirely sure how to answer. Basically everyone is entitled to their opinion and the blog reviews are the opinions of the reviewer.
Myself or the reviewer are not "doctors" we have no degree or formal authority. I like short blog posts; others like long blog posts. According to one side the other may be wrong but are they wrong? Everything is just a matter of preference and the point of the Bloggeries blog reviews is exposure and constructive criticism. So any criticism we may have is done in a positive light because they are our opinion and everyone is entitled to their own.
I understand you'd like more in-depth reviews and that may come in the future but it would have to be a paid service considering the length of time each review would take. At the moment they are being done free of charge and are a quick overview of the site ~350-750 words with a few deep links to interesting bloggeries and a keyword rich title and description. It is basically a here it is, what it's about, how it's setup, what we thought about it and how we thought it could be improved. There is no right or wrong answer as every blogs "worth" is in the eye of the beholder so we try and put a positive spin on everything even while offering criticism.
If you have suggestions for criteria I'm very interested in hearing your thoughts.
Thanks for taking the time to share your thoughts on this topic
