It's really an eye-opening training for me to do this Web2.0 training. I've learned a lot. I knew Googleearth before this training and I used it to find house pictures all over the world. To use Googleearth you have to download a software to your computer and then you can get a really clear photo of any house you're looking for. Now I know Google Maps and Wikicrimes etc. I knew there are lots of information available on internet and we can use search engines to search them. Now I know above these information appear those searching tools with Mashup technology to enpower or challenge us. How much information we can get from internet depends on how well we're good at using these tools!
