1. it's invite based?
2. it supports very few external services that you can verify (I can't figure out a way to verify LinkedIn or Gitlab for instance) ?

As for services, each service that's supported presumably needs custom code, and also needs to have a publicly-auditable way to post a proof that cannot be done by anyone other than the owner of the account (e.g. for Twitter you need to actually tweet something, for GitHub you need to post a gist, etc). I don't have a LinkedIn account or use GitLab so I don't know if those services have an effective way to handle such a proof.
For reference, here's a ticket asking for LinkedIn support - https://github.com/keybase/keybase-issues/issues/1115. Here's one for GitLab - https://github.com/keybase/keybase-issues/issues/1242 - which documents some barriers there (such as no API to get GitLab snippets).
