Interestingly, I noticed they're using Candara, which comes off looking pretty sharp. The interface is a huge departure, for the most part, from what was in version 3. Right off the bat, you'll notice the Flash graph that highlights the number of comments, entries, and tags (courtesy of Measure Map).
Hopping into creating an article, I was also very impressed with the look and feel of the default WYSIWYG editor. For those who want choice, you can also do Markdown, Markdown with SmartyPants and Textile 2.
The file and image upload features were probably my least favourite part of the editing process. Right off the bat, I discovered I couldn't close the image dialog unless I refreshed the page or uploaded an image. The dialog is also extremely slow to load (it's Ajax!!!). All files and images that get uploaded are stored in an 'organizer' that you can go into separate from the entry editing process. The upload process is also much nicer making it easier to understand where files were getting put in the site structure.
I also didn't much like the drop down menus. I find them distracting very quickly and can sometimes be a pain to get at what I want (like wanting to click on the home icon and having the blog menu drop down over top of it).
Some of the other big things that the MT folks are pushing is the registration system, allowing users to log in using a number of different systems like Vox and OpenID.
Editing pages also felt more intuitive, even though I sense that not much has really changed in this regard since version 3. Sometimes an interface change is all that's needed to make a feature more worthwhile (I'd put the recent Google Analytics redesign in the same category).
Unfortunately, I didn't really feel like much get added besides a new interface and better registration. Many of the more interesting features, like being able to clone a blog, are being handled by plugins, many of which were already available for MT3.
Spam protection seems unchanged. I fear how much spam wouldn't be caught by it in comparison to what I have now.
It's also still Perl at its core. This is one area that I think turns off developers. Not that PHP is a dream to program in but more people know PHP than Perl.
While the interface is very nice and there are some nice new features, I think they still have a long way to go before it'd convince anybody from switching back.f2富二代官网入口
