Twitter

I chose to draw the line with Twitter, I don't have smartphone, and my impression of the site is that it is most useful if you tweet regularly, and probably is most intelligently used by someone who is promoting themselves or their organization. I can see it being very useful to the library in that it provides up to the minute information about programming. The drawback of this being that if the information is not up to date ( as is unfortunately the case with some of the twitter accounts linked !!) then it can be a bit dssapointing.
I can imagine if i was a politician on campaign, or a musician on tour, that providing supporters and fans with new information about my wearabouts and appearances might be very useful. As for myself, I am quite happy with my current level of busyness, and not particularily keen to add more.

Google Docs

I have mentioned Google Docs previously for being one of my favorite online applications. It does make expensive software redundant, for this reason I have suggested it to several customers as a good alternative if they do not have the means to maintain a personal computer and software. For my part Doc's has allowed me to avoid having a personal laptop, and has facilitated many group projects where multiple people are contributing to the same document, or need to view the same information. I think that one of the very best uses for Google Docs is maintianing jobseach documents, Having a current, resumes, CVs, cover letters, project diescriptions and budgets avalable at the click of a mouse, even when somthing unplanned comes up is fantastic. This has been particularily usefull for me working in the arts, where there is an ongoing series of deadlines for grants, applications and artist calls.

Flickrititititi

yes, flickr and I are friends, i have been using flicker for at lest 3 years. As a visual person i really like the straight forward clean visual layout of the site, which is obviously geared towards people who like photographs, the cite is used extensively by professional photographers, and some major magazines like American Photo often print updates of the latest Flickr stars. Some of the best things about the cite: it links easily t0 other cites, blogs, facebook etc; it has it's own built in copyrite agreement, so your photos are automatically protected unless you specify them as part of the creative commons; there is a bundled photo editing application, with add on's. My favorite thing? There is no advertising on the site because pro accounts are administered by paid membership.
