When I talked with Tim, I had three ideas for monetization. His/Alex's may indeed be even better. #1 - Sponsorships/promotions on topically-specific "top" pages. Advertisers (like my company) pay top dollar for highly focused branding to specific audiences. If Trunkly created subject-specific pages like "Top Startup Links," "Top Travel Links," "Top Gadgets Links," etc. and earned decent traffic to them (which I think is very possible given how useful/interesting/powerful and SEO+social-sharing-likely those pages could be - think HN/Techmeme/Alltop/etc.) , that's a big advertiser revenue stream. #2 - Tools for management/analysis/tracking/enhanced data for specific users. I'd personally pay $10-$50 a month and my company would pay $100-$500 a month to have all our links not just tracked and indexed, but show data, signals and analyses of what predicts more clicks/shares/etc. I've always wanted something that could tell me which features (length, use of words, time of day, when I shared vs. others, etc.) predicted higher CTR/engagement/RTs/FB shares/etc. and Trunk.ly's well poised to build that. #3 - Social graph data ala Twitter + Facebook. Dozens of companies, in particular Bing + Google, are really interested in and paying top dollar for access to social sharing data about URLs. Trunk.ly knows not only what I share on Twitter/FB, but via my personal blog, LinkedIn, Quora, and anything with a feed that I add.
