Excluding the personal languages, constructed languages are internet languages. Except Esperanto, almost all pre-internet conlang’s languished and died. So if you are creating something other than a personal language, then the your internet strategy warrants some attention.
Choice of technologies
You probably don’t have much choice about technology because you need to go where the community is. The conlang community shows up on forums, mailing lists, micro-blogging services and many other special purpose websites.
Mailing Lists and Forums
These are closely related technologies. Forums cope a little bit better than mailing lists with high volume discussions. Members of the audience can unsubscribe from threads on a forum, while everyone received everything on a mailing list. On the otherhand, new threads on a forum are often ignored for days because often no one knows they exists.
Wiki’s excel for collaborative editing of documents. They also require a lot of co-ordination and trust amongst the audience.
Twitter and Shoutem
Twitter copes poorly with the fact that people have disjoint social graphs, i.e. a bunch of friends that speak one language and a bunch of friends that speak another language. However, as of right now, there are many more people actively using twitter. Shoutem works well for isolated groups, but because people don’t use shoutem very often, these accounts often become neglected.
