I've been following the WCG forum fairly closely since the GPU cancer project patiently waiting for when they would introduce another and you definitely get the sense that there is a lot of frustration about the fact that WCG hasn't made more of an effort to bring in another such project. When you think of all of the AMD video cards that are still out there that were being used for bitcoin, litecoin and other types of cryptocurrency mining, this is really a huge untapped resource and is something that might help to renew interest in the project.
As it stands, the number of active members in WCG continues to decline. It was nearly 90k in 2009 and we are now down to not even 65k as you can see here -

Just in the past 2 months we've lost about 2000 active users. The only reason the decline hasn't been steeper was because of the Computing for Good XRP giveaway which pretty much everyone on the forum trashed as being Satan incarnate. Oh, we shouldn't be paying people to crunch, yada, yada. In an ideal world, that's definitely true, but the number of people out there who are truly altruistic and only do things for the purest of motivations are few and far between. Fortunately many of them tend to congregate in teams like this, but if the overall trend is a decline in people contributing to working on projects like MCM, FAH and others that may come along, in the end, the goals of WCG end up not being served.
I've gone on my mini-crusades over there to try get WCG to putting some effort into building more of a community - the kind of community TPU and other teams have. But I suspect it's fallen on deaf ears. However as the participation rate continues to decline, the people at IBM who actually control the project will hopefully take notice - just like they did last year when they forced WCG to conduct their survey - a survey, which btw, had no user input whatsoever in terms of what issues and concerns should be included. Maybe next time they will actually try to involve us in trying to solve a problem that affects us all.
