The truth is that 6A have dropped the ball. They abandoned MT and their users, and their lack of support and updates has caused significant problems for even those people who are paying to use the software. Instead of keeping on top of MT and ensuring that it can cope with a rapidly changing environment and increasingly sophisticated spammers, they’ve spent the last 2 years focused on Vox.
sigh. at some point i will probably have to migrate to something else, but i won’t until it is really compelling and worth the considerable pain.
