I am unable to understand what is the activity on a question, as it shows the latest activity is 'today'. When i click on 'today' it shows the same page and same view and nothing there (interms of asnwers,votes,comments,comment votes, edits or anything new) that suggests of any activity. When I sort my questions it appears on top in order of 'recent'.The question i am referring to is this. The only thing i notice is there was some increase in number of views. Please let me know if i am missing something.
From your profile page you can see that that question was bumped by Community 12 hours ago. Even though there is no apparent lasting evidence of Community bumpings, I guess they count as "activity".
