A few comments.
Regarding the privacy concerns, the old profiles had the "Last Login" time the exact same as the new profiles. This is nothing new, and is handy for people wanting to see if you abandoned DN years ago, or if you are still active... and sending a PM to you wouldn't be a waste of time (for example).

And regarding the Fan Activity Feed (newly named), it does NOT show private messages (they're private!), but rather is only shows you what is already public. Every bit of information that appears on the feed could just as easily be obtained by visiting the user's public profile, this just saves a step for those people you find especially interesting.

But I do agree, there is a bit too much data, and that is defeating the usefulness of it. I'm about half-way done with an update to that system which should greatly improve it (less information flowing through, with better control/filters). Stay tuned.
Additionally, this entire website is about SHARING wallpapers, and expressing comments about them. It's a community built around public information exchange and collaboration. While this new system is quite radical, and a bit bold, I honestly feel it's a great evolutionary step for Desktop Nexus, facilitating the sharing of information and increasing transparency (of already public information). Facebook (et al) has already had incredible success with a model like this, and after it's fully adopted and the edges smoothed, I feel it could become very successful on Desktop Nexus as well. This is a huge technological leap for the very core foundation of our community, and again, while it's a bit radical, I truly believe if you give it a fair shot, in time it'll prove to be a very positive change.I am still actively looking for ways to allow further customization to a user's profile, such as custom themes/skins (via a great suggestion a page or two back). That's not going to be immediate, but in the near future.
I agree with another few previous posts, and I am planning on looking for a way to reintegrate uploaded wallpaper thumbnails into the profile homepages.
And yes, viewing all wallpaper comments you've received was an accidental omission from the new profiles. It'll be added back soon. Sorry!

I feel the journal entries are too disconnected. Maybe we should build a directory of recent journal entries submitted, or a listing somewhere of the "hottest" journal entries, judged by the number of responses they generate. What do you think of this idea? Any thoughts on how it could be implemented?
Regarding the PM system, previously there was an issue where if you're typing a long message and your session timed you out, it bounced you to the login page, losing your message. Yes, this happened to me too, but in this new system, I just finished a modification that should ensure this never happens again! Now whenever you send a message and your session times out (logging you out) before sending, it will detect this and prompt you to quickly log-in again (for security), before automatically continuing your submission and sending it. I'm not being very clear in explaining it, but I'm sure you'll all see if for yourself sooner or later. Hopefully it will save a lot of frustration.
This transition has rocked Desktop Nexus a bit, and I really do appreciate everyone's patience through it. Your feedback has been (and will continue to be) invaluable in my on-going development, tweaking, and bug fixing. I really do appreciate it!

Thanks everyone!
