I'm working on an open source project, and am looking to find collaborators. What's my best bet, in terms of advertising my project, with an eye specifically towards finding other developers interested in contributing?
This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions seeking career or education advice are off topic here. They are only meaningful to the asker and do not generate lasting value for the broader community. Furthermore, in most cases, any answer is going to be a subjective opinion that may not take into account all the nuances of a (your) particular circumstance." – durron597, Community
- Use Github to host your project, Github is the de facto service these days. It is easy and free to register, thus you are lowering the bar for the new participants.
- Create Twitter and G+ accounts for your project, This is really important.
You can use them to communicate with other developers and for announcement.
Why G+? because according to my personal observation, G+ is trending between developers mainly because we already have GMail accounts.
- Post about your project at sites like DZone.
- Many programming languages have sites named like language-planet.org
For example, I add an aggregator called ClojurePlanet to my RSS reader, I'm literally hearing/reading about new open source projects written in Clojure every day.
Use those aggregators to inform the world about your project.
One particularly interesting way of promoting your open source project is StackOverflow's own Free Vote-Based Advertising for Open Source Projects1:
Here’s how it works:
- Visit the special meta.stackoverflow.com question thread for this advertising period. It will always be tagged [open-source-advertising].
- Construct a 220×220 image advertisement for the open source project that you would like to publicize to your fellow programmers.
- Post an answer containing your image to the question. It must be in exactly the right format, as documented in the question itself.
- Get at least (n) upvotes for your answer.
- Your advertisement will now be featured in Stack Overflow’s remnant ad inventory, in the sidebar ad slot on most pages.
I think it will serve the
an eye specifically towards finding other developers interested in contributing goal finely, as the most visited sites of the network are geared towards developers (SO and this one) or technical savvy people (SuperUser).
I'm also very fond of Ohloh:
Ohloh is a new kind of software directory, combining community-driven content with a unique source code crawler that monitors up-to-date development activity.
Lastly, if your project relies on other open source projects, you could reach out to their communities.
And of course my answer is meant in addition to everything in Chiron's answer.

I agree with Chiron but I must add something more important: Your local LUG or whatever open source software you are using.
Also keep in mind, you are making a tool for a specific purpose, offer the solution to the users, some of them will probably encourage the development by testing it, making suggestions or actively developing the project.
Keep in mind that it must be useful, and it must be functional. Failing in one of those areas won't get you free man hours or compliments.
Get on podcasts! Herding Code, Dot Net Rocks come to mind. Also, get talked about on good blogs as much as possible.
Make your project useful, filling a gap in the people's needs. Find the users first - and some of them will become contributors later. The other way around is doomed to be fruitless.
