Who is using which? How do they compare? Does anyone use more that one? I've started using LT which I really like. Then found Goodreads and I've found the other participants are more active in GR than LT. AND then I found Shelfari and I really like their cool bookshelf for the widget but there's a lot of advertising. I really have attempted to analyze any but if you have strong pros or cons about any of these or know of others, please share.
I use LT mostly to catalog my books. I stopped cataloging when I got to the limit for a free membership about a year ago. But I just finally coughed up the money for a lifetime membership AND the bar scanner. Yes, I'm a big ol' nrrd.
I use GoodReads to find out what others are reading.
Haven't looked into Shelfari and won't...I have enough book things a going! haha...
I paid for a membership on LT also, so you're not alone. I haven't bought the cue cat yet. I'm sure I'll get one eventually. I blogged about this very issue last week. I'm thinking about joining GoodReads. I'll never leave LT though.
I use all three, and of the three, I prefer LibraryThing. It's easier to access and make changes to my library, quicker to change the cover if I have a different or rare one. The community is great there. It seems a bit more diverse as well -- a good combination of young and older readers.
The advertisements on LibraryThing are very unobtrusive and I rarely get spam from authors promoting their books. On GR and Shelfari, the ads are more visible and spam happens a lot more often.
I'm on LT and Good Reads, but spend more time on LT probably because I'm a creature of habit and landed there first. I also chat on Readerville.com, which I've been doing for years and years.
I really love LT--probably because it was the first I found, so I'm used to it. I think Goodreads is really good too. I have problems with Shelfari, only because it seems to take so much longer for pages to load on that site, and I'm not patient and start clicking to speed things up and then things get really slow! I do really like Shelfari's "what I'm reading now" widget though for my blog...it looks cool!
So many of you like GR that I just went over and signed up even though I'm an LTer. I, believe, I'm 'Marcia' at GR. If not then I'm 'the printed page'. I have one book listed and it's the one I'm currently reading, 'The Book of Lies' by Brad Meltzer. Now I just have work on getting my library imported, someday.
