So you pivot. Implement a feature that a niche will really like, but that the official Twitter app won't implement because it complicates things for those that don't care and fills a fairly small niche. For example, I'd love to have a client that lets me filter extremely powerfully. I should be able to filter by any field (for example, filter out whose source is Ad.ly because it's all ads), use regular expressions, etc. I think some apps come close, but I don't think any are quite as powerful as I'd like. Even if one is, there are plenty more niches to fill. An iPhone client that's not as pretty or feature-packed, but which loads instantly, for example.
