The cup is either half empty or half full. You can look at this list as a list of oversaturated markets or as a list of markets that have produced some great innovation and probably will continue to do so in the future. Hell, take Mint for example. They came after wesabe, fit squarely in the personal info space and are considered successful by most (not based on their sale, just the service). Looking at issue management: are Jira, lighthouse, trac, bugZilla, etc the best we can do? I doubt it. Fundamentally I think any idea you are passionate about is worth pursuing. Nevermind the judgements of naysayers and lists of supposedly typical idea space.
