I think my favorite part of doing this training was seeing the wide array of app choices. I'm now more likely to search for apps when I think, "There should be an app for that," and am often pleasantly surprised to find that there is an app or multiple apps. For example, during the course of 23 Things, I thought I was experiencing some decreased mileage on my car, so downloaded MileageKeeper to keep better track of this, and also temporarily downloaded an app to test my speedometer (turns out when I think I'm driving 70mph, I'm actually going about 67mph).
I didn't really connect with anyone via this training, but I did have a couple of friends like Katie of the Floating Lush who did the program, as well. When it's all over, I'll probably poke around and check out the blogs of those who completed the program.
Thing 9, I set a daily calendar reminder on my work calendar to write a blog post first thing each morning, which is the best time for me to write. Then, when on a good WiFi connection (at my parents' home), I went through and downloaded all the apps I wanted to try for all of the remaining Things. This way, I had them all on my phone (I kept them all on a separate page, in order, so I knew which apps were for the training) and could play with them whenever I had a lull at work, or see how they worked 'in real life.' This seemed to work really well for me, because then I was able to write a blog post days or even weeks after getting an app and having a lot of time to test it.
