You can definitely find tips if you search for them (and Lori (The Cowboy's Wife) offers tutorials for different things on her blog). Like Alyssa, I learned as I went. I've only been really blogging for about three months; before that I had the boring ol' blogspot blog that got updated 2x a year. Once I started playing with things, asking questions, and researching, blogging became much more fun!
Don't be scared to ask questions as you visit blogs -- if I see something on a blog tha tI like, etc., i'll leave a comment asking about it. Most bloggers love to help out!
Don't feel intimidated by how much there is out there. When you see something cool that you don't know how to do, just devote some time to learning that ONE thing. Ask around, search Google for a tutorial, and practice practice practice!
I am right there with you! I started my blog while pregnant with the baby and was starting to get the ropes. Now she is almost 2 months and I am finding it difficult to learn and also juggling her! I have gotten so behind that I went from having many comments on some posts to 1 or 2. Not that it matters, but that just shows me how little time I do have these days! I wish I could just buy a book because a book is easier to read one handed than going on the computer! If there is one let me know HA HA!
