I kind of agree. But I just use plain text files with bullets. I haven't seen a compelling argument to justify learning all the concepts and keystrokes of org-mode. I don't need all the bell and whistles. Export to HTML? Why?
If all you're doing now is plain text with bullets there may be nothing to gain. If, however, you have main bullet items that then have subitems, you'd gain the advantage of "collapsing" items (what in some coding environments is called "folding").
To get this benefit all you'd need to do is open a blank text file with '.org' suffix, then instead of bullets use an asterisk. Put one asterisk in front of main bullets, two asterisks in front of subitems. Then use key to expand or collapse subitems of current bullet item. Or to expand or collapse subitems throughout the document. That's all you need to get started using org-mode productively.
