The issue that blogs and other Internet news and analysis methods need to cover is how to generate primary revenue. Advertising revenue is a valid expectation and a big way to fund information sources, however it is fickle and if too prominent will devalue the trust in the audience. While newspapers did this with subscriptions it is very hard to envisage the genie making it back into that bottle with blogs. As long as there is someone willing to post information for free it is very hard for anyone to charge. Some niche areas will be able to build a revenue base from secondary sources, however the mainstream revenue model is yet to emerge.
