I think the other way around is also hard, many startups require such diverse combination of skillsets that its hard to know what you should learn in order to be hirable. As college grad student I have no clue what to learn to get hired by an "exciting" company. The only way seems to learn either the .net or the java platform as "safe" path, which in turn these exciting companies are not looking for.
