In a recent LinkedIn post, Niluka Kavanagh challenges conventional wisdom regarding professional social media conduct, highlighting what she terms the “7 deadly sins of LinkedIn.” Kavanagh boldly admits to violating nearly all of these perceived faux pas, arguing that embracing authenticity has, paradoxically, strengthened her brand and business.
Deconstructing the “Deadly Sins” of LinkedIn
Kavanagh outlines a list of behaviours often discouraged in professional circles. These include posting selfies, ending posts with a direct call to follow, writing in a corporate tone, sticking rigidly to a niche, commenting without genuine curiosity, using humour, and being “audaciously yourself.” She questions the prevailing etiquette, suggesting that strict adherence might be counterproductive.
According to Kavanagh, the common advice dictates a highly curated and impersonal approach. She specifically calls out practices that stifle individuality and genuine connection:
“Post selfies. This isn’t Facebook, Susan.”
She also critiques the often-repeated advice to avoid deviating from a narrow professional focus:
“Write like a human instead of a corporate memo. Unprofessional.”
The Paradox of Authenticity
Despite these widely accepted LinkedIn “rules,” Kavanagh reveals her own transgressions. She states directly:
“Unfortunately (or fortunately), I’m guilty of all seven.”
The core of Kavanagh’s argument lies in the unexpected positive outcomes of her unfiltered approach. She asserts that rather than hindering her professional presence, these authentic actions have led to growth. Kavanagh observes a trend that runs contrary to the push for highly optimized, potentially AI-generated content, suggesting that genuine human connection is more valued.
Human Connection Over Optimization
Kavanagh posits that the very qualities deemed unprofessional might be what resonate most with audiences. She notes:
“It’s almost like people prefer people…. over perfectly optimised AI content.”
This perspective challenges the status quo, encouraging professionals to reconsider the rigid guidelines often associated with LinkedIn. Kavanagh’s experience suggests that a more human, authentic presence can lead to stronger brand loyalty and business success, even if it means breaking a few perceived rules.
Her post concludes with an open invitation for others to share their own experiences, asking, “So… who else is guilty? Asking for a friend. 🫣” This interactive approach further underscores her commitment to fostering genuine engagement on the platform.
