Such is the difference between commercial development and open source. Open source developers can start a project as a learning exorsize or just because they individualy needed some feature. This isn't their day job and with very few exceptions they aren't paid to do this work. Packages are released when something works not when they're complete. Consider how many have version numbers starting with 0.something. In all fairness, complaining about what people share for free with others seems a little out of line. Don't forget that it frequently takes Microsoft 3 or more commercial releases before their products, which you pay for, start to be truely useful. As a consumer of open source software you have some choices. One is to get the code, join the team and work on the project yourself and the other is to donate to those that are.
