I really don't know if V3 will be ready this year. I hope so but time will tell. There is 100% certainty that we will se a working demo of V3 this year, but a release is way harder to do and requires a lot of debug, testing, debug, testing, etc. Otherwise I will have more than a thousand people complaining about it.
Regarding NSFW or family safe images, could be added but is not a priority for launch. Pay-per-view or anything like that is out of the question for initial release. Those systems rely on basic things like image upload, album management, etc... So I choose to focus in core functions and only when I felt good about it i will think in those extras.
AdSense? Sure.. a code block manager is easy to code.
First time i heard about IMAGE Space media, google tells me that is an ad service for images. Well, those things are just javascript, that can be directly added to the theme by you. Touching the theme is not hard and allows you.. well, absolute control of the output HTML
Member accounts will be added to V3 however there will be just one group. User groups could be added in the future but like I said, is not a priority.
This project is not a side project or a weekend job. I take seriously the job of building this product so I usually take my time to develop and release things. The Chevereto formula has been proved to be the best in the market so please understand why I prioritize things like an awesome user experience above profiting. Think about it, what is more easy to profit, a site with good or bad user experience? What is more important, have a pay per view module or actually have users using your installation?
Not to be rude but this is like the fortieth time that someone ask me these same questions this week. I've got these question rarely so many times that I'm starting to think that is the same person with different nicknames. Just me being paranoid.
