Hi N,
Some of us are still here. Like many hobbies, some fade in importance or priority after a while.
In my case, my "hobby" of investing I wanted to treat as a business. Therefore the business plan of Lichello's AIM became the basic structure and strategy of it. Once treated as a business, investing becomes less emotional and more consistent. The AIM engine is excellent for that low emotion and highly consistent goal.
Just as Day Traders tire of having to wear a catheter and not having a life other than staring at a monitor, some AIM users lose their enthusiasm. The ideas shared here and elsewhere about the AIM engine carried it from the "Senior Thesis" level to the "Post Doctorate" level. I'm sure there are other things that can be done/added/improved, but the incremental gains may be smaller than what has already occurred.
The AIM engine still doesn't address things like fundamental and technical analysis, portfolio design and structure, "core and satellite" ideas and market risk monitoring. Those things can and should be used in concert with the AIM business plan. Mark has complemented the AIM concept with several other products that reach into and help these other areas.
Best regards,
