Your point is perfectly understandable and certainly represents a wide slice of the market - which happens not to be the slice of the market we are ideally targeting.
We don't want to steal customers from logoworks, 99designs or other similar (very useful & well thought) services; we are trying something new here, pursuing an experimental approach to logo design, limiting to an extreme the user input in order to force the customer to get creative with tags - which could open the door to hopefully surprising results from our designers. That's the deed - if you're not quite happy you roll the dice and go again if you want, it's free.
Along the lines of the stir-fried culinary metaphor, we'd like to offer quality stuff on-the-go. This comes from the need of a category of people (and you can pull myself in) who don't wanna bother going through revisions and all that jazz.
This might not be the right service for you, and we won't try to convince you otherwise. If you're craving for Chinese take-away you won't go to the French restaurant. If you need a twitter account you won't get yourself a blog. And so forth.
Said so, your feedback and ideas are certainly constructive and valuable - thanks!
P.S.
The video is known problem (thanks for pointing out). You not liking the logos in the slideshow ... given the subjectivity of the topic it's bound to be a discussion with no end! :-)
