Good observation, Nicolas.
When I see that type of answer, I often wonder "What is wrong with the answer that they decided to also include a link to a list of apps?".
I then reread the answer at least one more time.
I've found that sometimes the answer is somehow lacking (does not really address all the feature requirements). In that case, I add a comment asking for more details.
Other times, I've found that the answer is great, but they are providing an additional resource in case the OP wants to see other options.
I get tempted to remove the link to the list of apps, but honestly, I sometimes find those links very useful, so I generally don't touch them. The big downside is that the links can become invalid, so the answer must always standalone as a valid answer without the link.
Regarding the meaningfulness of the votes, I understand your concern, and at the same time I personally don't find that to be an issue. I think most of the time people are voting for the software recommended, and not for the link to the list. I hope that if someone finds an equal or better solution from the linked list that they will post it as a separate answer, thereby helping our entire community.
