Hey James,
I actually found your stiqr.com through stumbleupon.com and been using it for adding and editing small changes on my website. Adding text and images is cool, but I think the embed function is awesome. I embedded youtube or other videos and drag it around on my site, lol. I tried embedding google adsense ads, and a website translator just to test it out, and it works too. I pretty much spend my time on what I can add to my website.
But I noticed that Stiqr is in beta, what happens after you guys launch? Do I have to redo the stiqrs again? Will I have to start paying? Any chance I can keep it for free since I'm giving feedback?
