I'm interested with many areas, but I can't thumb up all of them by tags. Why can't I receive questions with all the tags, then after some days' usage, I can remove the hated ones in the filter. I think it should be a basic functionality, if I'm wrong, please point out for me.
If you look under Your profile > Preferences you will find a favorite tags and ignored tags sections. You can simply add your disliked tags to the ignored section and select the "hide ignored tags" check box.
