I desperately wish Stirling wasn't a webapp. Having to setup and launch a web server and browser to edit a PDF on my computer seems insane. We skipped the "foss, local app" stage, where Adobe dominates, and jumped straight to the web service model.

I think the core audience for Stirling PDF is a lot different from ours. Stirling PDF looks like there built for enterprise users and big business. We built LuxPDF to be more for students, small business owners, freelancers, etc. To be honest we saw our site as an alternative to FreeConvert & PDFCandy, not for Stirling PDF.
