I currently use google images, groups and Picasa in my everyday uses. I use images the most. I put in a topic and I can find pictures of it. I sometimes find picture rather than web descriptions easier to navigate when I am look for craft and such. I belong to a few different groups. I am able to keep in touch with people and talk to the group an the topics that matter to us. We can share pictures files and have polls. I find both to be very helpful as well as useful.
