I recently joined LibraryThing, and I'm still figuring it out, as there is quite a lot going on, and I'm not the most tech-savvy.
Still, I've added the Currently Reading widget to my sidebar and I've entered in a small percentage of my books, those that I feel are most representative of my taste and my collection at large. At some point, I will get a paid account and enter them all, but that's an endeavor for a long period of time.
Among my most interesting discoveries so far have been early reviewer books that I can request, lottery-style, from publishers. I've done so for June, so fingers crossed! I've also been checking out recommendations based on my books, and I just found my library statistics, which are surprisingly mesmerizing. I've discovered that 52.17% of my favorite books were written by women, 47.8% by men and only 38.1% of the authors are alive, as opposed to the collections of 91% of other LibraryThing users.
Things may be slower as I've started work, but I will try to keep a regular pace. Reviews of the books I'm currently reading will hopefully be here soon!
