LinkedIn may be looking like a decent acquisition right now, but my god it feel awfully old to use, and I'm not sure how long the first-mover advantage will mitigate these shortcomings. Performance-wise, LinkedIn seems a step slower than not just Facebook or Twitter but even products from younger companies. The website is not very responsive, especially when displaying more than a few screenfuls of content, and the mobile apps are equally bad and lack any kind of smoothness.
