Thanks. I had posted that link earlier in a separate thread, but I came up with this list because I strongly feel there are diminishing returns in lists that are too long or whose criteria are too vague. I wanted to suggest a limited number of projects that, while perhaps different from Roam in key areas, are nonetheless viable projects that I feel could give Roam a run for their money on the long run. I just don't think there are that many projects that fall in this category...
