Just my 2 cents.
Edit: One more thing, designers don't create logos quickly. They're sweated over and tweaked and modified over and over until they're perfect. It's not something that we quickly generate or don't care about if there are small alignment/kerning issues. I'm sure there are some good use cases here but they don't immediately pop into my mind.
EDIT: Tried again, and realized the output is also the input.
However it isn't going to work as is. You need to show all fonts immediately. As a user, and potential paid user, I do not want to click endlessly.
I could see myself paying somewhere between $1-$5 for a zero-effort placeholder logo like this.
It could also find more varied use if you allowed the user to input more text at smaller sizes in order to generate Google Font based CSS for other elements of a layout (or to preview how a logo would look at a more realistic size).
I would suggest a slight redesign of the controls on the left so that it is clear which elements affect the font and which are purely for the shadow. Similarly, the "submission" of a shadow to the list of shadows needs a more obvious description (both verbally and visually) of how this process functions.
Overall, I think this is an excellent way of getting a (placeholder) logo up and running in 20 seconds and I'd love to see how you expand on its current state.
That's about it for now. Keep up the good work! Looks cool!
http://use.fontorie.com/5d90df57ffffffkkf000efn * The input box for the logo name is not obvious.
* The options on the left hand side are quite techy. I don't understand how they can help.
* Do all the four drop down boxes on the bottom work together? Or is it one font at a time only? The default view shows four active fonts. I was thinking that there was some cool algorithm which 'mixes' fonts. Is there any?* a suggestion: add a colour slider to allow changing the background colour of the page. It can be jarring whipping something up against a light blue background that's intended for a site with a different colour scheme.
* minor bug - when choosing a font from a different dropdown box (ie. picking one under "curvey", when the current selection is from "standary"), if the font is already the "chosen" one (ie. if the box was displaying "sniglet", and I click it again), the logo font doesn't refresh. It's not hard to work around (pick something else from the list, and then pick that one again), but it shouldn't be hard to fix either.
Other than that, I like it. Well done :).
I'd love it if I could get it as an image instead of CSS. Since I would only use it for a display and probably not any dynamic text, just a transparent png export of the image would be sweet. Even a non-transparent image export would be useful (and necessary with any amount of blur on the drop shadow).
On my own I can print screen and pull in the text into an image, resize it, and make it transparent but others might not have the resources or know how to do that.
One piece of feedback from how I would use this type of tool: Once I set my logotext, which I found not to be a problem, I would love to just jam on the down arrow on my keyboard to cycle through all. It sort of worked because it would open the last select used. but then it be pretty cool for my uses at least.
