It seems to me that every other month this certain company does something that is anti-their customer base, and maybe there's a market for people considering moving away from them? I've been inspired lately by the people who do Pinboard and Arq - both seem to be doing the one-man-band software thing, making something small and niche yet making a living out of it. Background info: Arq is a one-off purchase app that backs up to your cloud storage account (eg you have an AWS account with an S3 bucket, and Arq backs up to there). I was thinking of making a native Mac app Dropbox clone that would be much like arq (as in, BYO storage account). Eg it does automatic two-way sync of a folder to S3. Eg a company could have an AWS S3 account, and buy a copy of this app for each staff member, and they could all sync to the same S3 account. I'd charge like $30 for it, which is vs $120/year for dropbox, and your S3 / Backblaze B2 pricing would be tiny. Do you think this is crazy? Would you use it if I made it? Do you think it's a good enough idea to put on indiegogo / kickstarter / producthunt and see if there's any traction before starting on this? Thanks peeps
