Why are they keepers, according to you? Who would have an interest in them? Only you and for instance family because they are in them or it is about events they were part of? If so, why an online gallery?
There are (too) many meaningless galleries online, so first figure out your audience.

 Such questions ! ..... ask Flickr  ..... Facebook .... Smugmug .... etc ....... maybe they know the reason for their existence ....... (maybe, part of it is the pleasure of sharing)
 
.... your audience is a proportion of the general public ...... and there's absolutely no need to figure who they are .....

..... they will find you ...... whatever site you choose !!

...... strangely, although most sites welcome comments ..... criticism is generally considered bad form ..... and I never see it on Flickr.
