I would like a feed that includes every tag with the word "excel" in it. So I would get excel, excel-2007, excel-2003, and a few others. I have been subscribed to the excel tag, but I didn't realize there were other excel-related tags that I could be getting.
I can subscribe to each individually if that's the best way, but it does lead to duplicates and it's a heck of a lot of low volume feeds.
I can also combine the tags, but then when someone makes an excel-2010 tag, I'll have to know that it was made and update my feed settings.
I can accept that I might get tags that contain 'excel' that I don't want, but I can live with that.
Is there some existing way to accomplish this? If not and you want to implement it, I suggest
where tilde+keyword would include all tags containing that word.
