Thing 4 gave me the push to start using my twitter account created a couple of years ago, which was dormant. Been using for the past couple of weeks or so and got a wholesome count of 5 followers (no, not 5 m), wow! The pressure is building up - must start providing the goods. Amongst others, I am following @techno4learning, which is full of library techy stuff and Humanities.
Signed up to a few RSS feeds and made mental note about remembering to check Goggle Reader. Find it helpful to have all news in one place, less chance to get distracted.
Pushnote - well, don't know much about it so went around to find out more, especially to see what other participants thought of it. I found Bewo's blog very helpful and share her doubts about it's usefulness. Then came http://bethanarcpd23.tumblr.com/ which confirmed my thoughts - it will provide opportunities for reflective writing and to be an active participant of the online community. Time will tell how much use I'll make of it.
