BlogPress for iPad Sucks!!!
I used it for years - it seems like - without any problem, but it has stopped working. Apparently the developer doesn't see fit to update it, which is a shame. It was simple, fast and would let you write your own HTML without attempting to overwrite your tags with its own craven ideas. I hate blog apps that try to do too much - they make for more work than is necessary.
Equally as bad is how difficult to edit the webpage at blogger.com is - at least from iPad using Safari. So ... I switched over to a Windows laptop using Chrome.
Such is the life of a middle-aged slacker!
