Thats neat, just installed it to test. We sadly don't post much stuff that needs ocr'ing, although the occasional screenshot here and there is useful to ocr. Sadly I don't see that we would ever get over the 100 uploads a month limit.
In an ideal world this wouldn't even be necessary. This just speaks to the sad state of image format adoption and workflows. Every browser supports basic SVG. SVG text can be read by screen readers, indexed by search engines, found in the page, copied, resized, machine-translated, and everything else you expect from text. Why are we still taking raster images of text? I think the onus should be on the OS and browsers to implement snipping tools that can save in SVG. Regardless I still think this is a cool project for making that lost information accessible.
Yeah unfortunately I have to agree that the workflow just isn't there yet. (definitely a chicken-egg aspect to it) I can kinda see why, editing SVGs is completely different from editing raster images. (the former is pretty much code) The only reason I can see why image hosts don't support uploading it is because SVG has had some security issues. (don't know if this is still a factor) As for your point about most images not being text, I agree, but SVG does support embedding raster images so it would only be a small cost that yields all the benefits mentioned.
