There wouldn't be much point in a names board if people didn't use it to ask for people's opinions!
Fundamentally, the opinions of strangers shouldn't matter or influence us too much, but many find it helpful to hear how those names are generally received, especially as lots of people prefer not to discuss names with friends and family in 'real life', before the birth.
We do indeed all have different opinions, which is why someone simply saying "it's not to my taste" shouldn't put people off. However, a lot of the time people can point out a problem which OP might not have been aware of or even considered (for example, I'm guessing OP may now go away and Google the meaning of Pippa!).
You don't have to reply to such threads if you find them so strange or pointless 😉
