I'd suggest also mirroring the source repo to Github. Myself (and I presume others) often find interesting projects via Github's social and search functionality. Gitlab and Bitbucket don't currently have the critical mass for them to be worth checking in this way. Even if you prefer a different Git hosting service it might be worth also having a Github presence just to make it easier for people to find you. You can probably set the mirror to auto-update so it shouldn't need extra work once you've set it up.
