@silverstackeruk and @jk6276, I like the original vision of 1 million tokens. Steem has a tiny user base but that will change and when it does, it will change exponentially. I believe token sales will increase exponentially along with that, so I am wary of capping the fund. I feel we have only just got started, and there are many big ideas to come. It also concerns me that somthing like 70% of tokens are held within a dozen or so accounts: we need better distribution than that.
Having said that, I'd like to see much more off-chain investments, and a focus on building a portfolio outside Steem.
I think it would be much more interesting, engaging and in the interests of the SPI fund to have more member activity, including building investment awareness. Hearing people talk about what they invest in and why, the considerations for them and how they manage risk would enable people who feel they don't know much, or feel a little anxious about investing to take part and feel more confident about what they are doing. A monthly club meeting with a guest speaker with a nice clickbait title "why I wouldn't touch [property] with a barge-pole" (in fact, replace property with another word each month :D), would bring members together, build relationships and knowledge. Or a discussion about reserves (call it a buy-back wall, if you will) - are they important, pros and cons, how big should they be or some other topic relevant to understanding SPI and how investing works.
Fully understand about the grind of taking on a role like managing the spinvest-leo account, I've done similar things many times, which is why I'm not taking it on now as I'm approaching the end of my working life. I did consider whether I would do it if there was some recompense, as you are proposing. The answer was still "no"! I try to be a critical friend - ask questions, offer support, suggest ideas. That's what I can do for SPInvest.
I wonder whether there is any possibility of automating some of the more routine tedious bits of running an account - maybe consider the possibility of paying in steem/tokens for someone to do the development needed for automation or, if this is a problem that may affect many other tokens, asking whether there could be an automated system built into Steem-Engine. Should have written a post!
