The list itself - though not quite up to date - is still online on TheFoundry's community forum. It is not getting maintained (by me) any more and since, in the past, nobody bothered to help me with maintaining it, chances are great that it won't get updated again.
The database version has mainly been neglected by users, I logged about 1-4 visits to the database website per week. Let me repeat: One to four (unique) visits to the website PER WEEK.
I received almost zero feedback / encouragement from the modo community, therefor I don't really see a reason to have something up and running that isn't really useful to at least a reasonably sized group of people.
Absolutely, yes, of course! I would simply ask for the same thing that I have been asking for over the last (more than) three years: HELP. FEEDBACK. SUPPORT.
My plan, as explained to a TheFoundry employee, is to have a better, wider version available soon that supports not only modo but VFX, graphics, audio and other tools. But why not start with modo? If you want to help me, get in contact. Send me tutorial links with descriptive abstracts.
Depending on your point of view that may seem so. I felt that most submissions mainly self-advertised commercial tutorial producers, mostly without any usable description of the actual product - that I did not find helpful.
Personally I don't see any use in videos that merely show what one artist does, accompanied by some arbitrary audio-comment. And since I am not interested in watching (boring) or irrelevant (for me) paid tutorials just to get the required description, I still felt very alone.
Like I pointed out above: If I have to collect, edit and polish data all by myself, it just does not make any sense. The overall interest in modo is almost unnoticeable. My personal use of modo is now limited to working on the Trollbridge Project (until Mica's cloth sim is done, then I am probably going to stop using modo alltogether - it is just too slow and way too buggy). If I want to make money in the 3d world, I need to use tools that HELP me creating things instead of HINDERING me from it (or slowing me down). Besides, most of my professional modo-contacts (clients) have replaced modo anyway.
Let me give you an example:
I have created almost 100 (free) modo tutorials myself. Most of these got views in the low 2-digit area (like 10-20 views). I have seen many, many other tutorials with the same discouraging "impact".
On the other hand I got over 500 views on Vimeo alone within THREE DAYS after I published my first Houdini mini-tutorial. Vimeo isn't exactly the high-click-number website.
There just isn't enough interest in modo anywhere, there just isn't a cooperative community around modo (any more?) and there just isn't much to be gained from supporting modo (any more).
At least not respect - or money*.
