I think so but only when you humanise the brand. Logos don't have humour. People do.
When businesses are comfortable enough to put their employees in front of their logo, magic happens. Networks build. Connections thrive. Relationships deepen. All of this goes towards humanising the brand.
Obviously not all humour travels across borders but in most cases, "don't take yourself too seriously" humour can work to build empathy and trust with audiences.
I like the idea of businesses sharing their light-hearted side.
Humor's an essential element to being more human online because it’s another way that we connect as people in real life. People have shared humorous situations since the beginning of time, and across all communication mediums. When employed in the right context and as a part of your planned content strategy, humor can cement bonds, ease tension, even help smooth the way for collaboration. As with other types of content, context is important, and timing is important, so experiment and find the best mix for you or your company, but don’t leave humor out - it’s an essential part of human connection.
