Toonami is great for introducing children (and potentially adults) to the anime world. I still remember coming home from school and watching DBZ, Bebop, Gundam, Tenchi, etc. and I am very grateful to Toonami for that. I imagine it's the same for anyone else. But as an adult, I find it much easier and much more satisfying to watch BluRay releases, usually as a marathon.

I don't want to see Toonami disappear again, but I also don't expect it to go any further than it already has. It does it's job well.

On a related note, I don't remember the exact channel name (I think it was TechTV), but they had an anime block as well. I first stumbled across Gungrave on that channel.
