Here's an example. This question had some revisions to its title:

[Comparison of two convergence conditions for sequences of non-negative numbers](https://math.stackexchange.com/questions/1839/if-sum-n1-infty-fraca-nn2-is-finite-does-frac1n2-sum-i1n)

<https://math.stackexchange.com/posts/1839/revisions>

but when cited in the list of Related questions here

[If $\sum\_{n=1}^{\infty} a\_{n}^{3}$ converges does $\sum\_{n=1}^{\infty} \frac{a\_{n}}{n}$ converge?](https://math.stackexchange.com/questions/1766/if-sum-n1-infty-a-n3-converges-does-sum-n1-infty-fraca-n)

it appears with the title from revision #2 (of 3). It's currently the second-to-last one on the list.
