Hi guys- newbie here!- I'm planning on starting a site- probably more of a blog really, my coding skills haven't been updated since circa 1998 . It's going to feature a lot of input (hopefully anyway) from participants, and what I'd like to do is organize their writings, photos etc. on a world map which they/I can geotag, and have their entries appear as a preview on a side menu, or something like that. Any advice/links for me to go about doing this?

Many thanks in advance!
