PostEaseToo broad makes it hard to build a real identity
A creator covering everything loosely tends to build less of a distinct identity than one focused on a specific subject. A broad approach makes it harder for the right audience to recognize what an account is for, and harder to build the kind of topical authority that compounds over time.
Too narrow can run out of content faster than expected
A niche defined too specifically can run dry of new angles within months, which is a common and avoidable reason creators burn out or go quiet. Before committing fully, test whether the idea can sustain a realistic volume of content over a real time horizon, not just the first few weeks of enthusiasm.
The intersection of expertise and genuine interest tends to work best
A niche built around something a creator has real, first-hand expertise in tends to be more sustainable and more credible than one chosen by estimating audience demand. General interest is not enough. Expertise is also what makes it possible to keep finding new angles long after the obvious topics are covered.
