For several reasons:

1. There are many more English speakers (either as their mother tongue or as a secondary language) than Hebrew speakers. So I’m reaching a bigger target audience by writing in English.
2. Most native Hebrew speakers (i.e: Israelis) can read English well enough to understand my English writing. So most of the target audience for writing stuff in Hebrew will benefit from it very little.
3. I find it more comfortable and faster to type in English and express myself in writing using English for most types of writing (some stories I’m writing being an exception).
4. I often use a lot of tech jargon or slang, which is more difficult to translate to Hebrew.

That put aside, if you wish to translate a piece I wrote to any other language (including Hebrew), feel free to do so. I contributed some Hebrew translations to some English articles that other people originated, and also translated some things I wrote in Hebrew to English.

Note that I’m using Commonwealth English on this site. Partly because I think that’s what Israelis are supposed to use, partly because I have been somewhat British-oriented, and partly because it feels nicer to use an uncommon spelling. I am still using US English spelling for source code and for technical documents, though.

My thoughts are that both the British spelling and the American spelling (and their common subset), are inconsistent and confusing, but I have to make a choice of some sort.
