I expect the global economic situation may have something to do with it too:
Every organisation is trying to cut costs. Bringing IT in-house - DIY if you like - will be a common decision in boardrooms across the world I expect. Access is a DIY alternative to expensive bespoke databases. Managers and admin staff will be told "build your own system, we have the software to do that" and a lot of new people forced to get to grips with it. And at the same time government bureaucracies continue to expand (to meet the needs of the expanding bureaucracy) and that means organisations continue to need to store more and more data and need to automate as much as they can to keep staff costs from growing with it.
All-in-all I expect there's a lot of people learning Access now whom five years ago either would not have needed to or would have paid a professional database developer to do it.
And this is the best Access support forum in my opinion. It's only natural that these newcomers discover that too and register.
So, for us professional Access developers it's a mixed blessing. In the short term possibly less work - people try to do it themselves instead. But more Access databases out there should be good for us in the long run as these amateurs will need help and the more complex designs will, with all due respect, be beyond them (they haven't the time to learn it to that level).
The future of Access and the need for people who know how to use it (and the need for support forums like this one) is looking brighter than ever.
That is one of the reasons I'm happy to help here whenever I can (the other reasons being I quite enjoy it and it massages my ego
): It is helping more and more people up onto the learning curve. Most of them will probably never get close to the summit but if they get high enough then they will see the power of Access and will use it liberally. The more Access databases that are being used the more sure we can be that our expertise in it will continue to be in demand into the future. And that's not just good for me (us) but also on a philanthropic level: Greater understanding of Access around the world will improve productivity and efficiency and thus help global prosperity.
I welcome other peoples' observations and thoughts on that...
