That's a difficult question in some respects. One of the most vital aspects of community is, I think, Acceptance and it's a major part of the Book Blogging Community!
Starting and managing a book blog is a lot of fun and enormously rewarding. It can also be extremely over-whelming. Sometimes it may make you feel like your losing your mind! I love having a book blog and reading and reviewing books, as well as getting to know other bloggers is wonderful. But I learned not long after I began my book blog that I can only do what I can do. I discovered I have limits other bloggers don't have which, for me, stem from my health problems. I realized after pushing myself well beyond my limits that I may not be able to do things the same way or as much as other bloggers. This was difficult to accept. But, after a while I learned a very important lesson: that it's OKAY! It's okay if I don't read as fast as the next book blogger...or post a review everyday or every other day...or comment as frequently or on as many blogs as other bloggers...or leave as witty and amazing comments on every blog as other bloggers ...or post amazing, well-written reviews as some bloggers...and so on and so forth. It just matters that I do the best I can do, enjoy my blog and blogging as well as all that the Book Blogging Community offers!
And this same lesson applies to other Book Bloggers. We all have our issues and things going on in life that impact us in our blogging life whether it's a big family who needs our attention, a demanding job, health issues like myself etc. What's important is to remember who you are and to be that person in your blogging life. We're all different and we all have strengths and weaknesses. It's important to remember: You will be accepted for who you are in the Book Blogging Community. This is one of the greatest aspects of this Community: it is accepting of and accessible by every book blogger however and whenever you blog.
Like in real life, not every blogger will like you or your blog or be interested in you. And so what? Plenty will love you and your blog! Some bloggers want to talk books and blog books and that's all; some bloggers like to post about what's going on in their lives along with posting about and reviewing books; some bloggers review all sorts of products in addition to books! It's all okay. When you start blogging about books in some respect or other, you will find your niche in this Community and you will find other bloggers who accept you and your blog and whom you connect with and whose blogs you enjoy. There's room for everybody in the Book Blogging Community. If you love books and love to read, you and your blog will fit in in this amazing Community.
