We have recently opened a Geeklog room on Gitter as a replacement for IRC. Gitter allows developers to chat together online as a group, or in private conversations one on one. Gitter integrates well with Github (which Geeklog recently swithed too) including the repositories, issues and activities. You can access Gitter via their website and apps (iOS and Android).
The Geeklog room on Gitter is open to the public for viewing but you will need to create a free account if you wish to participate, ask a question or answer someone's query. If you are an aspiring programmer or seasoned developer and wish to particpate in developing Geeklog or coding a plugin, come and introduce yourself.
