A thought for a Sunday morning: what ever happened to Flock? It was just a few months ago that everyone wanted a peek at the new browser for Web 2.0 - but today's the buzz is gone, although it appears the company is still toiling away on new features. Perhaps this is the cruel reality of Web 2.0 - it's relatively easy and inexpensive to develop a new service/application but getting traction with users continues to be the real challenge. Flock had a big window of opportunity with an enormous amount of pre-launch buzz but it failed to impress when the alpha finally appeared on the scene. So what now? Is there still life for Flock and, if so, will anyone give it anyone shot? If there is a silver lining to Flock's effort is it demonstrates how Mozilla and Firefox can be used a platform to create niche-oriented browsers. Songbird is a great example where developers took the Firefox browser engine to build a cool music player. Here's hoping there are still developers willing to create a new browser. As Firefox demonstrated, there is demand for something different and better.
