I agree DW.
I used the InterAKT tools for a while, and the ADDT after that. It promised so much but I found it to be quite unstable at times, and the fact that you had to upload an entire framework (most of which was not used in my sites) was a really pain in the backside.
Also, if you needed to tweak the framework in anyway you had to have a real in-depth knowledge of the source code.
I find that the WA stuff is much easier for non-developers to use, and for people such as myself (I class myself as quite an experienced developer) it enables me to build solutions in a blink of the eye compared to hand coding from scratch.
I think the problem is that the extensions are so cheap and appealing that they are used by people who aren't developers, but are trying to put together development solutions. There is nothing wrong in this by the way, but its the mindset of a non-developer trying to 'develop'. I still use the term develop when using WA extensions because essentially, they help to aid development.
The WA products are not perfect but they are very, very good. The support is great, and the WA team have always been friendly when I have chatted on a remote session.
I am looking forward to future releases (Data Bridge?) and am excited about how I can utilise them into my future development.
To address the balance of the OP, Keep up the good work WA!
