Chasing tags across profiles is fun...
In our network, many member profiles have tags, so a fun way to explore the network is to:
(1) choose one member's profile page as a starting point (e.g. your own profile, if there are tags on your page), then
(2) choose one tag, click, and see what other profiles share the same tag.
(3) choose one of those profiles, and then a different tag, then click again...
One idea leads to another, and in the process, you can find people who are working with all of those ideas. We can call this process "people watching in the tag cloud". Bear this in mind when looking for someone to read or edit a manuscript.
People watching is not necessarily a frivolous activity, it can be important for your work.
