Could I watch a jira that I interst in?

[Brett Lee]

Hi all,

I'm new to jira issue tracking system. There are some jiras that I interest in 
and I want an mail notification if there is any progress. I see a watch link to 
do this but I found the exsisting watchers are almost major commiters of 
community. If I watch a jira that I just interest in but not doing any actual 
work, is it appropriate to do so?

Thanks!
