In short, we're too early.
I'd like to wait for a more secure setup so I can feel more comfortable putting up significant liquidity. I had a few forced closes earlier in the year, which I didn't think could happen. Then I learned a few things about how all the LN channels are linked by the nodes ID. So I'd also like to wait for better privacy before doing it again.
If I do do it again, it will be run as a business rather than out of interest.
