Turn off word verification - it's a bit of a pain in the bum having to do a word verification when you only want to leave a nice comment on someones post! So try and remove it as it will make commenting easier!
Reply to comments where possible - I think it's polite and shows you've read the comments, however clearly if there are thousands of comments on your post it would be rather time consuming to do!
Comment on other people's posts - it's a great way of talking to other bloggers and sharing your views and opinions with them
Post consistently - whether it be everyday or once a fortnight as long as it's consistent I think that's good!
Join in the twitter chats - they're fun and a great way to network and talk to other bloggers! HERE's a link to the Twitter chats!
Blog about what YOU want to - don't feel pressured to blog about certain things, products or people just because others are, just be YOU
Enjoy it! - If you're not happy blogging it will come across in your posts so if you don't feel like writing a post don't feel you have to, as long as you're happy nothing else matters!
Hope you found these tips helpful!
