Web 2.0 - mostly features, not companies
There are two things that strike me about the list;
- Each category is really crowded!
- Most of the categories are features that should be part of something larger, not large enough in their own right to be built out as a company.
It's worth spending time thinking about what categories haven't been established and where enough value can be delivered to build a company, not a feature.
The majority of categories and companies are consumer facing; the enterprise space for Web 2.0 looks like a good hunting ground. Let me know if you'd like to brainstorm ideas or chat about opportunities.
