What I have learnt from this unit and how I would use it

Oh boy, where do I start?!  This has  been an enormous learning curve for me.  I'll start with blogging, of course I had heard of blogs but never realised that they were easy to do and what an impact they can make.  Now I know what a QR code is (or rather boxes with squiggles in them!).  I managed to add a page to a Wiki and know what they are for and how to add  pages/comments.  I've read about posting photos on Flickr and embedding virtual tours of  the library. Of course there is Twitter and I enjoy following some of the big names I have chosen but as yet have not tweeted myself.   I must not forget Facebook where we would have a page. There are other Web 2.0 technologies that have been touched on but I have enough coping with the ones above.  I would love to be able to use these within our organisation, particularly for the library.  I would be able to make the library blog fun and interesting for the public to follow us and learn about the whole organisation.
I am particularly interested in our archival material and showing it off to the general public. These give a look at Australia through the photos and paper memorabilia that is unknown to Generation X.  They show a slice of life including fashions, attitudes and needs of Australia and Australians in different eras.  As an aside, it is such a shame that nowadays I find there seems to be little interest in keeping material for the future, especially photos as no one keeps digital images. They could be copied onto a CD and then kept in the archives.   I found this article on that exact point  The decaying web and our disappearing history       http://www.bbc.com/future/story/20120927-the-decaying-web/1   
To go on with how I can use Web 2.0 techologies within the library.  As I mentioned we would keep an up-to-date library blog which would involve news and views from the library and it's users; a virtual library tour; ask a Librarian; new material in the library - week by week; a link onto our home webpage; a QR code containing the archive exhibition and each month an article with photos of a particular year starting at the beginning 1939.  I would open a Twitter account to augment the library blog and a Facebook page. 
Something I will have to investigate is Flickr to post some of our archival photos and possibly a Wiki inviting readers to add their own comments etc.   I would love to become more involved with our members, library users and people just interested in what we do.
 I am sure that if we started using the above Web 2.0 technologies the benefit to the library and the organisation in general would be tenfold.
