I often ask niche or difficult questions, and I often get tumbleweed badges. 

Part of the formula is low views, so I find them quite useful as a notification that very few people are *looking* at my question and that I might therefore need to do more to get it seen. 

Ways in which I've responded to Tumbleweed before:

 - Migrating questions to a different site. For example, I asked a "Microsoft on Mac" question on this site, which went tumbleweed, so I asked for it to be migrated to Apple.SE, where it got a better response (and actually got a gold badge for over 10,000 views eventually!) 
 - Re-wording the title to make it more interesting or more obvious what the question is about. Sometimes my question titles were accurate but unclear or unappealing
 - Putting up a bounty.
 - Looking on other sites such as specialist forums - particularly if it's a very niche piece of software. Maybe there just aren't any regulars here who know that software. Linking to the question on a specialist forum can sometimes work (if the forum doesn't mind such things)
 - Sometimes, if you feel like you've done everything you can, you can put up a Support question on Meta linking to it along the lines of "What can I do to get this tumbleweed question seen?", and that itself might be enough to get an expert to notice the question (or, suggest a way to improve it)
 - Sometimes you just need to be patient. For example, [this very niche question](http://superuser.com/questions/605636/wiimote-accelerometer-input-on-windows-from-2013-onwards-glovepie-alternativ) got almost no response from the regulars, but got a great answer months later from someone else who was researching the topic, and is now up to 3,000 views because it's a rare source of quality info on a niche topic
