Personally I think it's fine, but it's also obvious that I read 37signals' post a while back re: their a/b testing and thought to myself: Hey, that's a great idea! Instead of doing a long form like everyone else, let's blow up a picture of a guy (me) on the left, put a video in the middle, and put some bullet points to the right with a signup button on bottom. Short and to the point, and incidentally, a technique that's been in use by print advertising since the beginning of print advertising.
So where exactly is the line? (and I'm asking because I'm truly curious if I've crossed it) 3 bullet points about your product is nothing new. The smiling guy you can relate to with a testimonial isn't new. Some screenshots or a product video above the fold isn't new. But I certainly wouldn't give myself a ton of credit for originality in landing page design. I guess I could put the guy on the right and bullet points to the left. I could move the signup bottom. I could have more content in my footer. How do you take the general concept and produce something that doesn't look like something of a rip off?
Personally, I have a lot of respect for what 37Signals has achieved over the years. So while I certainly want to learn from their mistakes and successes, I certainly don't want to be accused of being a scumbag design thief. Any thoughts?
