1. When I am watching trend or reading info on my airlines stocks Google AdSense is displaying advertisement of online travel ticket portal. Obviously if someone is interested in airlines stock that doesn’t mean that he is interested in traveling. This space can be use for more effective Ads.
3. The info displayed on Portfolio-related news page is redundant. ‘Recent quotes’ and ‘my portfolio’ section is showing same quotes as I just visited my portfolio. As people generally focus on their portfolio only, the info shown in these 2 sections will nearly always be redundant. Of-course Google can check if info for both these sections is same it can eliminate info from ‘Recent quotes’ section and use that space for something more fruitful, may be some more space for one more ad.
Am sure that Google folks are intelligent enough to mine web for feedback\ideas related to their products and soon they will give consideration to my tuppence as well.
