Whether you want to learn how to subscribe to your favorite blogs & podcasts with an RSS reader, or want to become a blogger / podcaster yourself, the links below can help you.
An RSS Reader is a software program / application that let's you specify which blogs/podcasts you are interested in (subscribed to), and will automatically alert you when new content is created on all of these, on a single page. Think of it like Gmail for blogs/podcasts, with a "inbox" showing new blog/podcast content for those you have subsribed to. Instead of visiting the site of every blog/podcast that your interested each day to see if they have posted anything new, you simply visit your RSS reader unread items page, and find everything new from all the blogs/podcasts you subscribe to.
feedly.com - an online RSS Reader.
Twitter.com - If you currently don't have a Twitter account you should get one. It can be used initially as your blog. Later, it will serve other functions. Since you will evenhutally need a Twitter account, you might as well start here if you currently don't have one. Plus, it's a good trial to see if your initeresed in blogging. If you can't blog a short 280 character post regularly, let's face it, you probably are not cut out for blogging. So, before you take the time and effort to set up a more complex blog, try a little micro-blog first. A Twitter blog also gives you the opportunity to gain experience of the mind set of blogging.
Medium - For complete newbies, I recommend this in combination with a Twitter account very highly. Get yourself a Twitter account first, and then immediately set up an assocated Medium account by identifying with your Twitter account. If your Twitter acount is @BobSmith your Medium blog URL will then be set up as medium.com/@BobSmith, and your RSS URL will automatically medium.com/feed/@BobSmith
WordPress - One of the most popular blogging platforms. Also, one of the more complex. Perhaps a good platform once you're experienced, but not the best platform to learn with.
Blogger / blogspot - owned by Google. Easier to use than WordPress, but it does have less features. Few downsides.
Tumblr - Originally bought by Yahoo, then sold to Verizon. Perhaps the easiest of all to use. A fine starter blog. But... Tumblr has some additional features that are not part of standard blogging platforms.
Twitter.com - both a blog & messenging system.
Twitrss.me - Get an RSS feed URL for your Twitter feed.
TweetDelete.NET - Let's you set your Tweets to automatically delete. You have options like 1 day, 1 week, 1 month, etc...
TweetDeck.com - Excellent Twitter tool if you are using are on a screen larger than a mobile phone. It allows you, amoung other things, to see multiple columns of tweets so you can watch (for example) everyone you follow, a watch list, notifications, your tweets, and messages all in separate columns.
It's not sexy, but it's universal, private & powerful.
Adding a link to allow folks to mail you from your blog/podcast allows you and your readers to talk together. Some prefer it to commenting systems, or social media because it is one-to-one, not speaking in a crowd. One of the things people find about comment systems, social media & chat is that trolls will often interject themselves into conversations, and then a crowd gets involved in a conversation, which diverts the original conversations. Think if it this way. If you're going to propse marraige to someone, do you do it in a crowd, or do you do it in private?
You can create a gmail account for free.
Use the Twitter & RSS feeds below (they are an aggregation of blogs & podcasts on the topics of literature, history & technology) to find some that interest you. Then subscribe to their individual blogs or podcasts with your RSS reader or Twitter, and then... eventually reach out to, and contact the creators of the ones you like, and perhaps ask them for some advice.
