I love music.
I'm not a very good guitar player, but I do play basic guitar so that I have someone to accompany me while I sing.
I write songs as well.
As far as rating, I appreciate any effort to post chords online. I don't care much for tab because I can't pick or play lead guitar worth a damn. Every song should have its chords and tab posted so, when it comes to rating, I focus on what I can use. A lot of the songs I search for have unbelievably wrong chords. I rate based on how much I have to fix. If I'm learning the song and have to fix the chords, I will almost always retab and post the chords.
