I have already had instances when Learning 2.0 helped me. Just this morning I needed to try to explain blogging to a patron. Not only could I explain what they were for, but I could show her mine, how to do a post, and other examples thanks to my blogroll! I could even tell her about technorati and explain how people find blogs.
The two biggest challenges have been time, and myself. Time, or lack thereof, is obvious. Myself meaning I got obsessive about some things. Like not being able to add an animation to a post. But I kept at it. I do believe that some of the tasks could use some FAQs, to help people troubleshoot.
My favorite activity was mashups.
The greatest benefit is that I am much more comfortable with web 2.0 tools, and will be utilizing and exploring them further. I look forward to helping others find their way with these tools, and finding applications for them. I will definitely keep blogging, I may even have a jewelry blog. And there wasn't that much I could find surprisingly about children and technology. Need to fill that niche.
I am thrilled to have been a part of the "original" learning 2.0, and happy it is being copied in so many other places. Thanks for the learning opportunities, and the opened doors.
