Some of the Tools that we have used in Exploring Technology that could be useful after graduating High School would be Google Drive. You could use Google Drive after graduating High School by sharing documents with others, being able to create a project for a class or even being able to edit other documents that others have shared with you. With Google Drive you can access Google Docs make word documents, powerpoint presentations, excel charts, graphs etc. all for free with a GMail account. I chose this tool because it is easy to use, free and you can collaborate with others if need be. Google Docs and Google Drive also automaticially save after every time you alter the paper, which can come in handy if you aren't such a great person to remember to save.
Probably a tool I would never use after graduating High School would have to be blogging. I am not the blogging type and to me, I always associate blogging with stay-at-home moms and I don't want to think that of myself. There is absolutely no problem with being a stay-at-home mom but I just don't ever want to not be able to work. Blogging isn't really something I find very interesting and to me it just gives me the ability to write nonsense. Blogging would be totally worth it if I got paid for it, but I don't so it doesn't really do much for me.
