Although this sometimes can be a disadvantage, it sometimes can be an advantage to communicate with others, as it allows me to share information and work that i've been done, it is actually a good way also there are more because on the internet as it is shared internationally.
The new people you meet on the net might be handy depending on there skills, so i could get quick feedback of what they think, a good way to get feedback. Alot of colleges ban alot of social networking site, so blogging can be another advantage which students can send feed back to each other, which colleges allows. students can be friends with each other whatever social network site is available, they could be friends easily by adding them by requests so it is easier to contact each other.
It is user friendly because it is easier to set up up work electronically and quickly. the network is free at college so you won't able to pay and blogging is also free to do. you get unlimited memoery on the net than offline. you can also show photos, charts and graphs to show your work aswell.
it is better than facebook, msn, twitter etc because you have to log in your account and you will have to link in with their account but in blogging, anybody can see what you have written.
