Yep, adding that option thing would be great. This could be done similar to the way giphy implements it at the moment. Also, guggy.com/slack doesn't seem to be working at the moment (along with the about page itself)
Just launched a new landing page, will be fixed shortly. Thanks.
If so, please make it an option like with giphy. I personally prefer the 'russian roulette' aspect to just firing and seeing what comes up :)
