Uhm, i use Share with English interface, but i'm still feel hardly to use it. To search some stuff on Share, i have to choose Cluster (keyword), choose nodes(similar to tracker in torrent), refresh nodes ( dont know why have to refresh, just follow tutorials) and search. After had search result, i dont know where to click download button, dont know to see something like ratio in torrent.
And the result usually in JP language, so i understand nothing.
All these programs were developed by japanese people, and meant to be used by them only. Now there is some english interface, but all the files are still written with kanjis, what do you expect ? There is no reasons to make things easy for western Gaijin (foreigners), they are not welcome in fact.
And no, they are not like Emule or a torrent client. Everything is made more difficult (anonymity, hash system) to avoid the japanese authorities to catch people sharing "illegal" material.
For your particular problems, why don't you read the nice Share FAQ already existing here:

Normally if you right-click on a search result, there should be an option called something like "add to download" and the file would show up on the Downloads tab.
When i download torrent, i still see many IPs from JP. And most of torrent apps can encrypt connections to make ISPs dont know you're using torrent. Why JP dont use simple P2P like torrent
Japanese will not use torrents to
upload files, because this too easy to get caught by their police. Downloading takes less risk since they are not completely "actively" propagating potentially illegal files according to japanese laws, at least they are not the primary uploaders.
You don't seem to realize that things coming from Japan like anime, JAV or J-music are obviously licensed in the land of the rising sun...
