Perhaps you could make some posts about LDS stuff; what you like and don't like
You could read blogs from Mormons, or other material by Mormons about their faith.
Do they have any different holidays than the mainstream Christians?
I think the holidays are the same.
Well, I don't think any religious text should be taken literally, so I can take Joseph Smith's visions as a dream or inspiration, but the idea that there were plates written in Reformed Egyptian, not a language, are not literal to me. It seems a stretch.
Did Jesus visit the Americas sometime? Again, I don't see that as literal, so not sure what to make of that idea.
The BOM, IMO, is not well written and really hard to understand. It has some nice verses, but it doesn't seem to have a cohesive storyline and some verses are almost identical, it's redundant.
The things I wish could be different: I wish they would do away with the garments. Since they have allowed exceptions to wearing it 24/7, why bother having it worn at all? Maybe at church, but so many don't wear it at all, especially women, since they are known to be uncomfortable and have caused UTIs and yeast infections, just don't require it.
I wish people could choose their own callings. I think a person will do a better job if it's something they have an affinity for.
I almost converted a few years ago, but about a week before my baptism date, I got cold feet. I just wasn't in 100%.
