Pro Tip: Install LGTM as a Google Chrome Extension. You can then LGTM with a click of a button.
LGTM.in is shutting down on 2018-10-01. I've been busy with a lot of things, and cannot spend time on this. The source is available on github.com/rahulsom/lgtmin and can be used to spin up a similar service. If you're interested in purchasing the domain and continuing to run this service, let me know, and we can work something out.
