I have the feeling that much of the frustration might also be due to a misalignment between the BTS team goal and who is actually present in the forums/using BTS. For me it seems that BTS tries to move towards business/commercial customers, whereas most people in the forums are 'hobbyists'. For larger corporations it might be really nice to revoke access and such, but for private use....not so much. I feel most of us in here would have been happy with a stable, reliable, simple version that uses keys to exchange folders and define access. That should have been the basis for a commercial product. Unfortunately, more features were added before a reliably working state was achieved. At this point I lost my trust in the core functionality of BTS. And at this point I do not really see why anyone would pay the $40 a year. Google and Dropbox have one terabyte for about $100 a year, but that included off-site storage, a nice web interface and most importantly - a reliable synching. I would have loved to remove my main data from the cloud, but not going to happen too soon. I hope you will prove the critics wrong!
