Went through the demo. Here is my advice:<p>1. The pitch of "instant blog theme to match your website" is a compelling one, and could lead to a profitable business model IMO.<p>2. For a version 1/MVP, I think it worked reasonably well.<p>3. However, I don't think it's a compelling enough feature to build YetAnotherBloggingPlatform and convince people to switch. I'm convinced Blogic would be way more enticing if you simply created themes for WordPress, Tumblr, and Posterous and charged $ for it. If you can scrape my site and build a blogging platform, then you can easily create the CSS/HTML/PHP necessary for these platforms.<p>Besides, do you really want to deal with 1000s of abandoned blogs, battling comment spam, and trying to play feature catch-up with these guys? (<i>"Posterous does X. Why don't you? WordPress has Y. Why don't you?"</i>) Trust me, you don't<p>Of course, this means you're now competing with the likes of ThemeForest, et al. But that's not a bad thing. They've proven that people will pay to make their blog look good.<p>My $0.02
