w7 twitters and delicious

I am not convinced to use twitters like Marcus' saying. But I did find someone recommend it as one of top tools for learning.

I like Heidi’s presentation of del.icio.us. When trying to use it, I found out tagging is really useful. And one tricky but interesting thing is that if I type “ concept map” in tags, it will automatically divide into two tags, concept and map. And in both tags, I will find the url I saved. In other words, one url can tag for more than one purposes.

For next assignment, our group decided to use google docs to collaborate our works. I am happy to explore this technology and find the advantage for saving the process of brainstorming.
