I like that they are easy for me as an individual user, because it is very simple! The application works great if you're just trying out different features or searching hashtags/keywords relevant at your business's industry type of content marketing (or something similar).
It can be difficult when there isn't much activity in any specific time period during which one would want them active with tweets - but this may not have anything directly related anyway? So far so good :) If anyone has questions about using twitnodes within our organization feel free ask us!! We use these tools daily by both myself personally & my team members who work remotely from home while we all operate together through TeamViewer software throughout each day via internet connection sharing between laptops / desktops etc...
