The only problems, and these may be big for some, and what keeps this from being a great component are several things.
1) They don't allow comments in articles. They strip a lot of code out of articles which include any commenting system you have. This is a major loss for most bloggers who rely on user input.
2) The app is very slow sometimes and pages sometimes even hang without ever loading
3) The app also strips out any videos you may have in your article and as we know many articles you write are based on the video you place within.
Overall review: For a paid component, these simple fixes should be addressed and if corrected/added it would completely blow the competition away. If I'm going to pay 40 dollars a month it should be able to do what a free component does and more.
Joomla should have a much better way for us to migrate over to 2.5. I'm completely lost on how I'm going to do this. This certainly is no help whatsoever
