it isnt going to be plain sailing for the edge aggregators. The low barrier to entry means that all these services will face defensibility issues – whats to stop a barrage of newcomers aggregating exactly the same content? Being early in the game may lead to beneficial network effects, but maintaining this advantage is always a challenge. Whats more, services like Edgeio plan to transfer content both in and out of the system – it seems plausible that others could take advantage of the resulting output, with or without Edgeios explicit permission. Yet more critics wonder whether the need to have a blog may limit the potential of such aggregators. Personally, I dont see this as a critical issue: edge feeders allow you to create syndicated content without owning a blog, and even centralized sites may see the benefit in becoming edge feeders and/or aggregators.
