Pros
Pro IFTTT Integration
You can easily create Inoreader recipes. For example, you can have an Inoreader recipe that will automatically publish to a blog any content you label with a specific tag in Inoreader. That is just one example; there are all kinds of ways you can use IFTTT to integrate Inoreader with other platforms and tools.
Pro Turn Twitter, Facebook, and Google+ content into RSS feeds
In addition to subscribing to regular RSS content, you can use Inoreader to subscribe to Twitter, Facebook and Google+ accounts and, even better, you can use Inoreader to export that content in the form of RSS. So, if you want to make a combination RSS feed of all your activity at Twitter and Facebook and Google+ plus all your blogs, you can do that, exporting all your social network activity as a single RSS feed.
Pro Premium users can search in all public RSS feeds, even in those that they haven't subscribed to
Pro Rule-based tags to sort and organize content
You can create rule-based tags in Inoreader to sort and tag incoming content across all the feeds you are subscribed to based on keywords and other elements. If you subscribe to lots of RSS feeds and want to sort and organize your incoming content, Inoreader rules are incredibly powerful.
Pro Create combination RSS feeds to export with RSS
You can create folders and/or tags in Inoreader combining content from different feeds into a single feed of its own which you can then export via RSS or display with an HTML clippings view. Remember YahooPipes? Like that, but better. If you like to share what you are reading or if you want to reshare your own content from multiple blogs with a single RSS feed, try out the amazing Inoreader export options.
Cons
Con Price change / Feature capping instituted
Inoreader just announced that the "Professional" plan will be capped (big change is from unlimited filters to just 30!):
Based on our observations, the new premium feature limits on the “Pro” plan are as follows:
10 Rules
30 Active Searches
100 Boosted Feeds
30 Social media feeds per service (Facebook, Twitter, VKontakte).
These limitations will be applied to your account at the start of your next subscription period. All features that you use above the new limits will be deactivated, and only those that were created earliest chronologically will remain (For e.g. your earliest 10 Rules created)
