Well, saying I am loving Backdrop is perhaps expressing it a bit strongly, and what I really mean is that I very much like this excellent product, in the same way that I love our 'new' car - a VW Golf Plus Automatic (now 4 years old), our new kitchen, even my Laptop now that it has been rejuvenated with maximum RAM and a Solid State Drive. These are things that work really well.
I am currently developing three small websites using Backdrop, one of which is a definite prospect and the other two are strong prospects, so watch this space for more news. This is valuable real experience that is convincing me of the benefits of adopting Backdrop. Much as I have liked Drupal 7 as a flexible tool there is plenty of scope for improvement and Backdrop is achieving this. There is still an occasional need for a specialised add-on module but normally it is a fairly straightforward matter to port a module across from Drupal; oh the wonder of open-source! To meet specific needs in current work I have recently added 'Google Fonts' and 'jQuery Expander' to the Backdrop portfolio of contributed modules.
I am still working on the much less exciting task of trying to get the Date module fully working within Backdrop. This is proving quite a slog as I work though the existing Drupal code and find out why it is throwing up errors in Backdrop. If I had a better understanding of how the rather complicated Date module actually works and better familiarity with the PHP language, I would make faster progress. Much of this is planned to be provided in Backdrop's core in September; hopefully my efforts will be a slight contribution towards this.
The really big step forward in September's release 1.2 will be the incorporation of a WYSIWYG editor. At the moment I get by quite well with my port of the CKeditor module which works just as well as it does in Drupal, but the new integration is going to be a great step forward, and there is not long to wait.
My next area of interest? I must get to grips with theming in Backdrop. In Drupal I have tended to use Zen and tailored it mainly through stylesheets. In Backdrop I am currently doing much the same using the Bartik theme as a basis.
Thanks Backdrop team for a great product, and also the fabulous support you provide through the 'issues' system.
