No it's not remotely like saying “should I make my ecommerce site look exactly like Amazon?" Sheesh, Mr. Bradshaw. Think over what you're saying: Amazon has 30 million regular customers, its website is the #9 visited website on the Internet, and 61% of all American consumers polled knew of the Amazon Kindle. Do you really think you have 30 million readers, or that 3 people out of 5 know what Svbtle is?
I think Svtble bloggers must be vastly overestimating the numbers of their readers. I've been reading a variety of blogs since years before they were called blogs, and I've never heard of this group or "network" before today.
That said, ask yourself if you'd want people to accidentally associate you with a group as cliquish and territorial as this one seems to be.
