"So far the only app I released (Autumn) was a bust because I stupidly released it on New Year's Eve so practically nobody knew about it" Virtually no business

"So far the only app I released (Autumn) was a bust because I stupidly released it on New Year's Eve so practically nobody knew about it" Virtually no businesses work like this. Maybe NY Eve wasn't the best date, and it's great if you get a boost from the announcement, but you need to follow up with marketing, continue talking to customers, sales, calling people, etc. Most users will not hear about your business from the initial announcement. A lot of times when you see a business take off after an announcement, it's because they worked for months prior to build an audience. Sometimes that's the developers audience (if you have a lot of twitter/blog/etc followers), or it can be because you preannounced it, collected emails, and kept them engaged as it was being developed. You still need a game plan for after the announcement though. Good luck... try not to get discouraged if it's not an immediate success. (Your other point, about it being too niche, can be a problem if that niche isn't valuable enough.)
