Well, for what it's worth, there's no special advantage here to working with raw. I mean, you can open a jpeg original in Lightroom and do with exactly what you would have done with a raw original. It's non-destructive editing either way in Lightroom (and Picasa, and many other programs). To me, the important point is that there is no DISADVANTAGE to using raw. A few years ago, before Lightroom and Aperture and the other first non-destructive raw workflow programs, working with raw generally meant running the raw originals through a converter, to produce jpegs, and then working on the jpegs. Now, there's virtually no difference in Lightroom between one file format or the other.
As for the statement, "you can always make further edits...", this also needs, well, not a qualification so much as a caution.
You can always go back and make further edits to a raw file
if you continue to use the program in which you made the previous edits. In other words, the work I've done in Lightroom in the last couple of years can be reviewed, tweaked etc, in the future - so long as I keep using Lightroom. But if I take a photo already edited in Lightroom, and then open the raw file in (say) SilkyPix Pro Studio 4, to see what I could do with it there, I'm automatically back to square one, because SilkyPix isn't aware that Lightroom has ever looked at the file.
This is why, in my opinion, it's important to process photos fairly soon after you take them and save your work by exporting a high-res jpeg. I'm not worrying here so much about the very real possibility that all of these digital file formats may become obsolete - and sooner rather than later - as I am worrying about the more mundane possibility that I'll decide NOT to upgrade to Lightroom 3 and move instead to some other more attractive program in the future. (Unlikely, but, you know, I like to keep my options open.)
Once again, this isn't a disadvantage of raw, exactly. If you had thousands of jpeg originals instead, and you'd edited them in Lightroom, you'd lose those edits, too, if you moved to another program, and the problem might even be worse because it's easier to get confused about what is the original if you're comparing two jpegs, where if you have a raw and a jpeg copy of the same image, you know which was the original.
The concern I'm expressing here also pertains to asset-management products. I think it's really important to store as much metadata as possible in the IPTC area of the file, since that's a standard that can be read by all programs. Titles, captions and keywords all get stored in IPTC. Unfortunately, things like gallery assignments and ratings do NOT get stored in IPTC. That's part of the reason why I do NOT spend a lot of time building custom galleries either in Lightroom or in Picasa (where I manage my processed jpegs).
