It is great that we have the auto-completion of tags in the search box. When I enter i.e.
then all the SQL tags get included in my search automatically and I have a live refresh on them in a single browser tab. That way I can watch my favorite tags in real time on Stack Overflow which is really awesome!
Manually I can enter up to 250 characters in the search box. But with this auto-completion I can overcome this. Try i.e.
[*api*] or [*sql*] or [*xml*] or [*css*]
You can extend that to watch almost everything in SO in realtime. Is that OK?
