Google Trends was just launched recently.

I checked the functions and compared it to BlogPulse which is online since a couple of years.

If you search for “PS3” – Play Station 3 – for example you see a very goood search results with completely new criterias.

Here are some of the most important functions:
– News Volume compared to Search Volume.
– C ategorization and Selection of Years, Period and Regions.
– Major milestones are marked with arrows.
– Major news-articles for these milestones are presented on the right.

What should be improved?:
– There is no number of the news volume listed. At BlogPulse they show the percentage rate of the trend, which is helpful.
– Show translations of major news-articles, too.
– Compare it to Google Zeitgeist and show differences.
– etc….

Any more ideas?
